Peripheral blood lymphocytes from normal subjects as well as patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and active tuberculosis were studied for the relative distribution of bone marrow-derived lymphocytes (B-cells) and thymic-derived T-cells. B-cells were identified by direct immunofluorescence of surface Ig markers; T-cells were studied using rabbit antisera ...

However, it has not been detected on eryCD33 antigen (glycoprotein M, 67,000). detected by the monoWe successfully detected the expressions of CD33 antigen on norclonal antibodies (MoAbs) MY-9 and Leu-M9, is in highest conmal human peripheral CD4+ T and CD8' T lymphocytes that were centratio...

Human peripheral blood T-lymphocytes adhere to myelinated sections of human and nonhuman brain tissue. No lymphocyte adherence is seen to gray matter. Lymphocytes from patients with MS adhere more than control lymphocytes. Lymphocyte adherence in patients with stable MS and in healthy controls did not vary more than 15%. Lymphocyte adherence in MS patients was decreased significantly during exa...
