Antigenic correlation between rat thymus and superior cervical ganglion.

By using rabbit anti-rat thymocyte and anti-rat superior cervical ganglion sera in cytotoxicity, immunofluorescence and absorption assays, it has been shown that surface membranes of rat thymocytes and cervical ganglion cells (i.e. peripheral nervous tissue cells) contain common antigenic determinants.

In vitro cross-reacting antibodies from rabbit antisera to rat brain synaptic membranes and thymocytes.

Rabbit anti-rat brain synaptic membrane and anti-rat thymocyte antisera were used in cytotoxicity, immunofluorescence, and absorption assays to define the antigenic relationship between the rat brain and thymocytes, and the localizing properties of antibodies. Both antisera cross-reacted with brain tissue and thymocytes. However, anti-synaptic membrane and anti-thymocyte antisera also contained antibodies specific for neurons and thymocytes, respectively. Immunofluorescence showed that antibodies from anti-thymocyte antiserum reacted with antigenic determinants situated on the surface membrane of brain cells.

Antigenic correlations between chicken brain organelles, thymocytes and bursacytes.

Rabbit antisera to chicken whole brain and brain microsomes, synaptic membranes, and synaptic vesicles were used in cytotoxicity and immunofluorescence assays against chicken bursacytes and thymocytes. Brain organelles, bursacytes and thymocytes have shown to possess common antigenic determinants. The common antigen is present in small amounts on thymocytes and can be demonstrated only by immunofluorescence.

Potentiation of experimental allergic thyroiditis in rats adipectomized at birth.

The effect of neonatal extirpation of the interscapular brown adipose tissue (adipectomy) on the development of experimental allergic thyroiditis in 8-week-old inbred Lewis rats was studied. The incidence and intensity of disease were much higher, and delayed skin reactions significantly stronger, in adipectomized rats than in control sham-adipectomized rats.

Bursa lymphocytes and IgM-containing cells in chicken embryos bursectomized at 52-64 hours of incubation.

A technique of surgical removal of the bursal primordium ("bursectomy") of chicken embryos at stage 17, approximately 52-64 hours and 29-32 somites, is described. The survival rate of bursectomized (Bx) embryos approached a level of 50% on the 21st day. About 20% of correctly Bx embryos exhibited malformations of the anal sphincter and the large intestine. Using a rabbit anti-bursacyte serum, which did not react with thymocytes, the specific bursa-derived cell (Bu) marker was detected on the surface of bursa, spleen, bone marrow and thymus lymphocytes. Early embryonic bursectomy caused a moderate depletion of Bu marker-bearing and IgM-containing cells. It has been postulated that embryonic Bu cells can be recruited from sites other than the bursa and in the absence of the bursa.

Preparation of specific anti-thymocyte and anti-bursacyte sera in rabbits.

A method of producing anti-thymocyte and anti-bursacyte sera in rabbits is described. Chickens which served as donors of cells were thoroughly perfused with saline to remove plasma proteins and circulating blood elements. For immunization, thymocytes were obtained from neonatally bursectomized birds, and bursacytes from chickens thymectomized at hatching. The purification of rabbit anti-lymphocyte sera included absorptions with leucocyte-free suspension of chicken erythrocytes, chicken liver cell membranes, thymocytes from bursectomized-irradiated and bursacytes from thymectomized-irradiated chickens, and chicken IgM and IgG immunoadsorbents. Cytotoxicity and fluorescent-antibody assays revealed that anti-thymocyte and anti-bursacyte sera thus produced clearly distinguished the surface antigenic determinants of thymocytes from those of bursacytes.
