Distinct patterns of HIV-specific memory T lymphocytes in HIV-exposed uninfected individuals and in HIV-infected patients.

BACKGROUND: Repeated exposure to HIV is not always associated with infection and multiple cohorts of HIV-exposed but seronegative individuals (ESN) have been described. HIV-specific CD4 and CD8 T lymphocytes are detected both in HIV patients and in ESN; we verified whether different patterns of HIV-specific memory T lymphocytes would be detected in individuals in whom exposure to HIV results or does not result in infection. METHODS: Gag-specific T cells were analysed in 15 ESN, 14 HIV patients, and 15 healthy controls using extensive flow cytometry analysis. RESULTS: Data confirmed that gag-specific T lymphocytes are present in ESN. Gag-specific T cells mainly secrete interleukin-2 in ESN and interferon-gamma in HIV patients. In addition the CD4/CD8 and the memory/naive ratios are altered, central memory (45RA-/CCR7+) CD4 and CD8 T lymphocytes are more abundant, and terminally differentiated (45RA+/CCR7- and 27-/28-) CD8 T lymphocytes are augmented in ESN individuals. CONCLUSIONS: Exposure to HIV occurs in high risk seronegative individuals; the observation that naive cells and CM are skewed in ESN indicate that this exposure is robust enough to modulate the CM/EM ratio. The increase in late effectors and in natural killer cells seen in ESN suggests a role for these cells in preventing actual infection.

Decrease in pathology and progression of scrapie after immunisation with synthetic prion protein peptides in hamsters.

Effective therapy for prion diseases is currently unavailable. Recently, vaccination was shown to be effective in mouse models of a particular neurodegenerative conditions: Alzheimer's disease (AD). Here, we report that vaccination with synthetic oligopeptides homologous to the hamster (Mesocricetus auratus) prion protein augments survival time in animals infected intraperitoneally with 263K scrapie agent. For each hamster included in the study, prion-specific serum antibodies as well as deposition of pathological prion protein (PrP(res)), glial fibrillary acidic protein (GFAP), and mRNA expression for cytokines (TNF alpha, IL-1beta, IL-10) in brain tissues were evaluated. In immunized animals, increased survival after challenge was associated with a reduction of cerebral lesion, PrP deposition and GFAP expression; in these animals, anti-prion protein peptide antibody levels were increased, and the expression of pro-inflammatory cytokines (TNF alpha and IL-1beta) was reduced. Vaccination could be an effective therapeutic approach to postpone disease onset.

Programmed cell death of myelin basic protein-specific T lymphocytes is reduced in patients with acute multiple sclerosis.

We investigated the apoptosis of myelin basic protein (MBP)-specific T lymphocytes in multiple sclerosis (MS) patients with acute (AMS) or stable (SMS) MS by evaluating the expression of apoptosis markers on peripheral cells. Cells of healthy controls (HC) were evaluated as well. Results showed that mitogen-stimulated apoptosis was comparable among patients and controls, whereas MBP-stimulated CD4+ and CD8+ 7-AAD+ and 7-AAD+ Fas+ cell (apoptotic cells) were significantly reduced in AMS patients. A reduction of the apoptotic rate of myelin-specific CD4+ and CD8+ T lymphocytes could be involved in the immune-mediated destruction of the myelin sheath seen in AMS patients.

Human alpha defensin in HIV-exposed but uninfected individuals.

Human alpha defensins 1, 2, and 3 are produced by CD8 T cells of HIV-infected long-term nonprogressors and have an antiviral activity. alpha Defensins were examined in peripheral blood mononuclear cells (PBMCs), cervical-vaginal mononuclear cells (CVMCs), and cervical biopsies of 9 HIV-1-exposed but uninfected women (ESNs), 10 HIV-infected patients (HIV), and 13 low-risk healthy controls (HCs). Results showed that, whereas alpha defensin production and alpha defensin-expressing CD8 lymphocytes were comparable in ESNs and HIV patients, constitutive alpha defensin production by peripheral CD8 and CVMCs was augmented in ESNs compared with HCs (P = 0.001 and P = 0.058, respectively); alpha defensin mRNA was increased in PBMCs of ESNs; unstimulated, alpha defensin-expressing peripheral and mucosal CD8 lymphocytes were 10-fold higher in ESNs compared with HCs (P = 0.003 and P = 0.01, respectively); and alpha defensin mRNA and alpha defensin-expressing cells were augmented in cervical biopsies of ESN compared with HCs (mRNA:P = 0.03). The differences were reduced upon in vitro mitogen stimulation. A robust constitutive production of alpha defensin is seen in HIV-exposed uninfected individuals; these peptides could have a role in the potentially protective immune response that characterizes ESNs.

Granule-dependent mechanisms of lysis are defective in CD8 T cells of HIV-infected, antiretroviral therapy-treated individuals.

BACKGROUND: HIV-specific cytotoxic T-cell (CTL) responses are defective in HIV-infected patients undergoing antiretroviral therapy (ART). This defect has been attributed to the decreased antigenic burden secondary to ART-associated suppression of HIV-replication, and is responsible for the rebounds of viraemia that occur when patients interrupt therapy. CTL are stimulated by type 1 cytokines and can kill targets via granule-dependent (perforin and granzymes) and -independent (tumour necrosis factor-alpha, CD95) mechanisms. METHODS: Granule-dependent and granule-independent mechanisms of CTL killing, as well as type 1 cytokine production by CD4 T cells, were analysed in 57 chronically HIV-infected ART-treated or ART-untreated individuals. RESULTS: The results can be summarized as follows: the frequency of gp160 (env)-specific interferon-gamma-secreting CD8 T lymphocytes correlates positively with HIV viraemia in ART-treated and -untreated patients; Env-specific perforin- and granzymes-expressing CD8 T lymphocytes, and Env-stimulated perforin and granzymes mRNA, are reduced in ART-treated patients independently of HIV viral load and of type 1 cytokine production; tumour necrosis factor-alpha production is increased in ART-treated individuals; and Env-specific immature CD8+28+27+ cells are only marginally augmented in ART-treated patients, Similar results are observed in cytomegalovirus-specific CD8 T cells and peripheral blood mononuclear cells. CONCLUSIONS: A defect of CTL function that selectively affects the granule-dependent mechanisms of lysis is observed in ART-treated individuals. Because interferon-gamma production is higher in these patients, this could be a defect primarily involving CTL. These data suggest an independence of CD8 T-cell numbers and their lytic ability in HIV-infected, ART-receiving patients. Immunomodulants are needed to successfully treat HIV infection.

Interleukin-2 immunotherapy exerts a differential effect on CD4 and CD8 T cell dynamics.

BACKGROUND: Emerging evidence indicates that CD4 and CD8 T cell recovery is differentially regulated during HIV infection. The hallmark of interleukin-2 (IL-2)-induced immune reconstitution is the selective outgrowth of CD4 through undefined mechanisms. OBJECTIVE: To delineate the effect of IL-2 on T cell homeostasis by analysing the differential impact of IL-2 immunotherapy on CD4 and CD8 dynamics. DESIGN: A randomized trial of 15 HIV-positive patients, eight receiving IL-2 immunotherapy with highly active antiretroviral therapy (HAART) and seven with HAART alone. Patients were followed for a 48-week period following three IL-2 cycles (overall, 10 weeks in duration). METHODS: CD4 and CD8 count, naive and memory immunophenotype, proliferation by Ki67, and CD8+CD38+ activated pattern were measured longitudinally by flow cytometry. Thymic output contribution to both CD4 and CD8 was evaluated by measurement of T cell receptor excision circles (TREC). Wilcoxon test was used to compare results. RESULTS: Compared with changes seen with HAART alone, IL-2 induced a more significant rise in CD4 than CD8 T cell count (P < 0.01), associated with a significant increase in Ki67-proliferating CD4 (P < 0.05), whereas no changes were seen in CD8+Ki67+ (P > 0.05). Furthermore, IL-2 administration was associated with CD4 TREC increase, whereas CD8 TREC remained stable (P > 0.05). Modifications in CD4 and CD8 T cells seen in patients taking only HAART were not associated with changes in CD4 and CD8 TREC. CONCLUSIONS: By showing a differential impact on CD4 and CD8 homeostasis, the study suggests that IL-2-associated immune reconstitution results from protean interactions between T cell compartments; this has significant implications for the correct planning of immunotherapeutic strategies.

Growth hormone in T-lymphocyte thymic and postthymic development: a study in HIV-infected children.

OBJECTIVES: Growth hormone (GH) plays a role in thymic function, and recombinant GH may stimulate thymopoiesis in HIV-infected individuals. We performed immunologic analyses in 26 antiretroviral-treated children matched for age, pubertal status, clinical parameters, and antiretroviral exposure who did or did not show an impaired response to GH-release stimulation tests with arginine + GH-releasing hormone. RESULTS: The following abnormalities were found in GH-deficient compared with GH-nondeficient children after >4 years of therapy: CD4 count ( P = .02) and percentage ( P = .03), CD4 as percentage of normal cells for age ( P = .003), serum interleukin-7 concentration ( P = .02), and thymic volume ( P = .01). Naive CD4 (4+62+RA+ and 4+CCR7+RA+) and CD8 (8+CCR7+RA+) lymphocytes were lower in GH-deficient children ( P = .003; P = .007; and P = .02, respectively). Postthymic pathways were also impaired in GH-deficient children. Thus, central memory (4+CCR7+RA-) CD4+ cells were reduced ( P = .006), whereas effector memory (4+CCR7-RA-) CD4+ cells ( P = .002) and late effector CD8+ lymphocytes (8+CCR7-RA+ and 8+27-28-) ( P = .009 and P = .002, respectively) were increased in these children. CONCLUSIONS: Growth hormone plays a role in thymic and postthymic pathways, and defective GH production may be associated with incomplete immunoreconstitution. Immunomodulant agents (including GH) could be useful in patients with defective GH production.

Interleukin-10 and interleukin-6 gene polymorphisms as risk factors for Alzheimer's disease.

In the pathogenesis of Alzheimer disease (AD), it has been proposed that the anti-inflammatory interleukins such as IL-10 regulate beta-amyloid-induced microglial inflammatory responses inhibiting the proinflammatory cytokine IL-6. Since the promoters of the IL-10 and IL-6 genes show single nucleotide polymorphisms (SNPs) (IL-10: -1082 G --> A; IL-6: -174 G --> C), we investigated these SNPs and cytokine production by peripheral blood mononuclear cells in 65 AD patients and 65 controls (HC). In AD there was a significant increase of the -1082A IL-10 allele (P=0.009) and a decrease of -1082GG genotype (P=0.019). The frequency of the GG IL-6 genotype in AD was lower and the C allele significantly higher (P <0.005). The co-occurrence of IL-10 A and IL-6 C alleles significantly raised the odds ratio (OR 11.2, confidence interval: CI 1.3-97.3; P <0.05) independently of apolipoprotein E4 (adjusted OR 10.3, CI 1-108; P <0.05). Only amyloid-stimulated IL-10 production differed between the groups (P=0.023). These results raise questions regarding the inflammatory theory in AD, pointing to a pivotal role of IL-10 and IL-6 and a selective alteration in this network.

IL-7/IL-7 receptor system regulation following IL-2 immunotherapy in HIV-infected patients.

Interleukin-2 (IL-2) and IL-7 are the most intriguing molecules in immune-based HIV infection treatment. An in vitro IL-2/IL-7 cross-talk due to IL-2-driven IL-7 receptor-alpha-chain (IL-7R alpha) down-modulation, potentially blocking IL-7 signalling has been described. We investigated the in vivo IL-2 effect on IL-7/IL-7R system, measuring free IL-7, and IL-7R alpha CD4 and CD8 in 12 HIV-positive patients enrolled in a randomized IL-2 trial. Compared to HAART alone, IL-2 induced a parallel expansion in total and naive CD4, TRECs and IL-7 plasma levels, with no IL-7R alpha CD4 and IL-7R alpha CD8 changes (P>0.05), suggesting that in vivo IL-2 boosts IL-7 production without down-modulating IL-7R alpha, preserving IL-7-mediated T-lymphocyte homeostatic regulation. Our data confirm the pivotal role of IL-2 and IL-7 in the regulation of T-lymphocyte homeostasis in HIV infection.

Immunomodulation induced by tucaresol in HIV infection: results of a 16 week pilot Phase I/II trial.

OBJECTIVE: Immune reconstitution in highly active antiretroviral therapy (HAART)-treated individuals is incomplete and immunomodulatory compounds are needed to improve the outcome of HIV therapy. In a Phase I/II clinical trial performed on HIV-positive patients we analysed the safety and immunomodulating effects of tucaresol, a novel compound that has previously been described tn enhance cell-mediated immune responses. PATIENTS AND METHODS: Sixteen weeks pulse dose escalation protocol. Four groups of HIV-positive patients were enrolled: group A (n=6): HAART, CD4+ 300-500 cells/microl, HIV RNA <80 copies/ml; group B (n=6): HAART-naive, CD4+ <500 cells/microl, HIV RNA >10 000 copies/ml; group C (n=3): HAART-naive, CD4+ >500 cells/microl, HIV RNA <10000 copies/ml; and group D (n=6): HAART, CD4+ <200cells/microl, HIV RNA <80 copies/ml. Tucaresol was added to HAART in group A and D patients; group B patients started tucaresol with HAART, group C patients received tucaresol alone. Clinical and immunological analyses were performed at different time points. RESULTS: Tucaresol-related serious adverse events were observed in the first week of therapy in 2/21 patients who were viraemic when commencing treatment, but did not occur in patients on stable HAART. Tucaresol did not affect HIV viraemia whereas increases in CD4+ percentages, mainly supported by naive CD4+ cells, were observed. CD8+/28-/45RA+ cells and HIV-specific CD8+ IFNgamma- and perforin-producing cells improved whereas IL-10 mRNA diminished in tucaresol-treated patients. The effects were greater with 25 mg given every other day for 1 week. CONCLUSION: In HAART-receiving patients with proper virus suppression, tucaresol was not associated with serious adverse events and resulted in qualitative and quantitative stimulation of HIV-specific cytotoxic T lymphocyte activity and generation of naive T cells. These data may support further exploration of tucaresol use in reconstitution of immune system parameters in HIV patients with proper virus suppression while on HAART.

Functional repertoire of dendritic cells generated in granulocyte macrophage-colony stimulating factor and interferon-alpha.

Monocyte-derived dendritic cells (DCs) generated in granulocyte macrophage-colony stimulating factor (GM-CSF) and interleukin-4 (IL-4-DCs) are used to enhance antitumor immunity in cancer patients, although recent evidence suggests that their functional repertoire may be incomplete; in particular, IL-4-DCs appear unable to induce type 2 cytokine-producing T helper (Th) cells. To assess whether type 1 interferon (IFN) could replace IL-4 and generate DCs with a more complete repertoire, we characterized in detail DCs generated from human monocytes cultured with GM-CSF and IFN-alpha (IFN-DCs). We found that IFN-alpha induces DC differentiation more efficiently than IL-4, yielding similar numbers of DCs in a shorter time and that this differentiation persists upon removal of cytokines. Although IFN-DCs had a more mature immunophenotype than IL-4-DCs, showing higher expression of CD80, CD86, and CD83, they still preserved comparable endocytic and phagocytic capacities and responsiveness to maturation stimuli. IFN-DCs had strong antigen-presenting capacity, inducing intense proliferation of T cells to alloantigens or influenza virus. Moreover, IFN-DCs produced lower levels of IL-12p70 and higher levels of IFN-alpha, IL-4, and IL-10 than IL-4-DCs. As a consequence of this different pattern of cytokine secretion, IFN-DCs induced T cells to produce type 1 (IFN-gamma) and type 2 (IL-4 and IL-10) cytokines, and as expected, IL-4-DCs induced only Th1 differentiation. As immune responses with extreme Th1 bias are considered inadequate for the induction of optimal, systemic antitumor immunity, the ability of IFN-DCs to promote more balanced cytokine responses may suggest the advisability to consider these cells in the development of future, DC-based immunotherapy trials.

IL-4 and CXCR4 upregulation in HIV-infected and uninfected individuals from Maharashtra-Mumbai.

We extended the investigation of the virus-host interaction in developing countries by analysing Indian HIV-infected and uninfected individuals from Maharashtra-Mumbai. Results showed that CXCR4 messenger RNA and surface expression, as well as IL-4 mRNA and T allele frequency at the -589 site in the IL-4 gene (high IL-4 production) were significantly increased in Indian compared with Italian individuals. Because IL-4 stimulates CXCR4 expression this observation could be explained by the higher frequency of the -589T IL-4 polymorphism.

Assessment of immune reconstitution to Pneumocystis carinii in HIV-1 patients under different highly active antiretroviral therapy regimens.

The introduction of protease inhibitors (PIs) gave a dramatic drop in AIDS-related opportunistic events, mainly due to induced immune reconstitution. Discontinuation of prophylaxis against Pneumocystis carinii is considered safe when CD4 > 200 cells/mm(3). Ideally, we should have specific functional tests for HIV-1-related decisions. We examined viro-immunological profiles, clinical outcome and lymphocyte proliferation (LP) to P. carinii and other antigens in 108 subjects: 28 AIDS presenters with P. carinii pneumonia (PCP) (CD4 < 200 cells/mm(3)), 22 untreated asymptomatic HIV-1-infected patients (CD4 > 200 cells/mm(3)), 44 HIV-1-infected patients immune-reconstituted on antiretroviral regimens and 14 HIV-1-uninfected healthy controls. As regards viral load, there was no significant difference in therapy duration, nadir, or actual CD4, CD8, natural killer or B cell counts in immune-reconstituted patients receiving protease inhibitor (PI)-based versus those receiving PI-sparing antiretroviral regimens. Among subjects showing abnormally low P. carinii-specific LP, three patients receiving a non-nucleoside reverse transcriptase inhibitor (nNRTI) developed PCP despite having CD4 > 250 cells/mm(3). P. carinii-specific LP could be considered for doubtful situations, i.e. for a safer clinical decision of discontinuing or restarting prophylaxis in patients with a low CD4 nadir or experiencing a sudden CD4 decrease under highly active antiretroviral therapy (HAART). HIV-1 PIs, having in vitro aspecific effects against Pneumocystis, could play a clinically significant anti-opportunistic role, thus offering a further benefit in heavily immunosuppressed patients during early stages of antiretroviral therapy.

Mucosal and systemic HIV-1-specific immunity in HIV-1-exposed but uninfected heterosexual men.

BACKGROUND: Despite multiple, repeated exposures to HIV-1, some individuals never seroconvert. Mucosal and systemic immune correlates of this condition have been analysed in HIV-1-exposed women but no data are available concerning mucosal immunity and HIV-1-specific immune responses in exposed but uninfected men. DESIGN: We analysed cellular and humoral immune parameters in peripheral lymphocytes, seminal fluid and urethral swabs of 14 recently HIV-1-exposed seonegative (ESN) heterosexual men, seven HIV-seropositive patients and seven healthy controls. RESULTS: HIV-1-specific IgA were detected in urethral swabs of 11 out of 14 ESN and of six out of seven HIV-seropositive patients; Env- and Gag-specific IFNgamma-producing CD4 and CD8 peripheral lymphocytes were present in ESN and HIV-seropositive patients; seminal lymphocytes, but not peripheral blood lymphocytes, of ESN were enriched in activated populations (CD8CD38RO and CD4CD25). p24-specific cytotoxic T lymphocytes were correlated with the percentage of CD4 in the HIV-seropositive partners. High urethral concentrations of HIV-1-specific IgA were seen in those ESN with the most recent unprotected sexual episode. CONCLUSIONS: This is the first report of HIV-specific mucosal immunity in ESN men. These data add to the body of knowledge of the immune correlates present in exposed, uninfected individuals and might be important in vaccine design.

Distinct immune profiles characterize patients with diffuse or limited systemic sclerosis.

Mitogen-stimulated IL-2, IFN-gamma, TNF-alpha (type 1 cytokines), and IL-10 (type 2 cytokine) production by peripheral blood mononuclear cells, as well as expression of surface markers on immune cells, was evaluated in systemic sclerosis (SSc) patients. Fifty-four SSc patients with either diffuse (dSSc) or limited (lSSc) disease and 20 age- and sex-matched healthy controls (HCs) were examined. Fourteen patients were treated with prednisone and 9 patients with prednisone and cyclophosphamide pulses. Results showed that (1) IL-2 production is significantly decreased, whereas IL-10 is higher in untreated patients compared to HCs; IL-10, IFN-gamma, and TNF-alpha production is higher in lSSc compared to dSSc patients; (2) CD4+25+ (IL-2R), CD8+, and CD8+45RA-28+57- (memory) lymphocytes are reduced in patients compared to HCs; (3) CD95-expressing CD4+ and CD8+ cells are significantly higher in dSSc patients; and (4) steroids are more effective alone than in combination with cyclophosphamide in reducing IL-10 and IFN-gamma production in these patients. These results confirm that a complex imbalance in cytokine production is present in SSc patients and suggest that peculiar phenotypic populations are underrepresented in these patients. Overexpression of Fas in dSSc could results from the attempt of the immune system to induce apoptosis of autoreactive T-cell clones.

Research on psychoimmunology.

Several lines of evidence suggest a role for the immune system in the multifactorial pathogenesis of schizophrenia and other psychiatric and neurodegenerative disease. Later, the role of immune mediators like cytokines became a source of main interest related to the process on inflammation in the CSM. In this article we report the results of our research on cytokines in a different groups of psychiatric patients following their clinical symptomatology and the course of diseases. In particular, we observed a prevalent type 1 cytokine profile in acute multiple sclerosis patients, while IL-10 production predominated in stable multiple sclerosis individuals. The modifications of cytokine profiles observed in schizophrenic patients suggests that clinical improvement is associated with a reduction in the inflammatory-like situation present in those not currently under treatment. Our data on Alzheimer's disease (AD) support the role of the inflammatory process in the pathogenesis of AD and reinforce the hypothesis that the neurodegenerative processes in the AD patients are associated with an abnormal antigen-specific immune response. The activation of immune system mechanisms observed in obsessive compulsive disorders could be due to the combination of endogenous (hormonal alterations associated to the modifications in the hypothalamic-pituitary-adrenal axis) and exogenous (viral or bacterial infections) factors.

Cytokine production in women with antiretroviral treatment-associated breast fat accumulation and limb wasting.

OBJECTIVE: To test the cytokine production of peripheral blood mononuclear cells in a group of HIV-infected women with breast enlargement and lower limb wasting while receiving antiretroviral therapy (ART) including a protease inhibitor. DESIGN: Case-control study including 20 women with fat tissue alterations and 20 matched controls treated with comparable ART. METHODS: Adipose tissue alterations (ATA) were defined by increased breast size (> or = 2 bra sizes) accompanied by lower limb fat wasting. A randomly selected subset of patients underwent analyses including: dual energy X-ray absorptiometry, metabolic and endocrine assays, in vitro cytokine production testing [interferon-gamma, interleukin (IL)-2, IL-4, IL-10, IL-12, tumor necrosis factor-alpha (TNF-alpha)] after appropriate stimulation; T-cell phenotyping, T-helper function after stimulation with either tetanus toxoid, influenza antigen, allogeneic peripheral blood lymphocytes, and phytohemagglutinin. Endocrinological study included the determination of plasma concentrations of prolactin, growth hormone, testosterone, adrenocorticotropic hormone, cortisol and C-peptide. RESULTS: In vitro production of IL-12 was higher (P = 0.0001), and TNF-alpha (P = 0.0093) and IL-10 (P < 0.0001) production were lower in stimulated peripheral blood mononuclear cells of ATA-positive women compared with ATA-negative women. ATA-positive women also showed a better response to tetanus toxoid (P = 0.021) and a lower median fluorescence intensity of CD14/DR (P=0.033). Plasma C-peptide values were higher in ATA-positive women compared with ATA-negative women (P = 0.033), even if in the normal range (< 4 ng/ml) in all but one of the ATA-positive patients. CONCLUSION: HIV-1-infected women who developed breast enlargement and lower limb fat wasting while receiving ART had a favorable immunological profile with efficient IL-12 production and T-helper function, and with TNF-a production in the range of a HIV-negative reference population. These findings suggest that the rescue of some immune functions under ART may be involved in the pathogenesis of this particular adipose tissue disorder.
