WEHI-231 B lymphoma cells have proven to be a useful model for the regulation of growth of normal B cells by anti-Ig reagents. We previously reported that the growth of these lymphoma cells is inhibited by heterologous or monoclonal anti-mu or anti-kappa reagents. Such cells cease to incorporate thymidine within 24-48 h of exposure to anti-Ig reagents, but(More)
It has become increasingly apparent that B lymphomas provide clonal models for antigen-specific lymphocytes and for the analysis of both positive and negative signalling in B cells. In addition, anti-Ig reagents have been used to mimic antigen/tolerogen in their interaction with B cell receptors at a polyclonal level (1-3). We have been studying the effects(More)
Spleen and bone marrow cells from DBA/2 mice protected against infection with a leukemogenic dose of Friend leukemia virus (FLV) by passive therapy with chimpanzee anti-FLV serum were shown to be able to adoptively transfer antiviral resistance to unimmunized irradiated syngeneic recipients. Similar to the results obtained with donor mice immunized against(More)
BACKGROUND Health care associated transmission of Mycobacterium tuberculosis (TB) is well described. A previous survey of infection control (IC) practices at clinical research sites in low and middle income countries (LMIC) funded by the National Institute of Allergy and Infectious Diseases (NIAID) conducting HIV research identified issues with respiratory(More)
