Lymphoid cells producing antibody against simple haptens: detection and enumeration.

Enumeration of cells producing antibody against arsanilic acid was made feasible by the use of hapten-conjugated sheep erythrocytes for the localized hemolysis-in-gel technique. The time of appearance and numbers of these hapten-specific plaque-forming cells correlated closely with the development of arsanilic acid-specific serum antibodies.

A mathematical model and CD4+ lymphocyte dynamics in HIV infection.

The paper presents a model of CD4 + lymphocyte dynamics in HIV-infected persons. The model incorporates a feedback mechanism regulating the production of T lymphocytes and simulates the dynamics of CD8 + lymphocytes, whose production is assumed to be closely linked to that of CD4 + cells. Because CD4 + lymphocyte counts are a good prognostic indicator of HIV infection, the model was used to simulate such therapeutic interventions as chemotherapy and active and passive immunization. The model also simulated the therapeutic administration of anti-CD8 antibodies; this intervention was assumed to activate T-cell production by activating a feedback mechanism blocked by the high numbers of CD8 + lymphocytes present in HIV-infected persons. The character and implications of the model are discussed in the context of other mathematical models used in HIV infection.
