Rabbit anti-rat brain synaptic vesicle serum reacted with thymocytes and B lymphocytes in cytotoxicity and immunofluorescence assays. Quantitative absorption analysis revealed that this antiserum contained antibodies specific for antigenic determinants on the surface membrane of a subpopulation of rat bone marrow B lymphocytes.
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.

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.
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.
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.

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.
