1. Molecular genetics of B- and T-lymphocyte development
Abstract : Lymphocytes are essential for the generation of specific immunity. Development of B cells in the bone marrow and T cells in the thymus have several analogous features, and are tightly regulated processes. Even though there is an increasing amount of information concerning lymphopoiesis, a lot of questions remain. READ MORE

2. Murine B lymphocyte growth regulation : a study of host defence factors and their mimicry by Mycoplasma arginini
Abstract : Immune responses are the result of extended clonal growth and maturation of specific precursors preexisting in low frequencies. Clonal expansion is partly controlled by soluble factors, thus, their identification is essential for the understanding of the immune response regulation. READ MORE

3. The B lymphocyte in Staphylococcus aureus arthritis
Abstract : Joint infection caused by Staphylococcus aureus leads to heavy synovitis and rapid destruction of bone and cartilage. Permanent loss of joint function is seen in 20-50% of the patients, despite early eradication of the bacteria with antibiotics. READ MORE

4. Regulation of B cell development by antigen receptors
Abstract : The developmental processes of lymphopoiesis generate mature B lymphocytes from hematopoietic stem cells through increasingly restricted intermediates. Networks of transcription factors regulate these cell fate choices and are composed of both ubiquitously expressed and B lineage-specific factors. READ MORE

5. Development of the gastrointestinal tract in young mammals : Effects of enteral provocation with protease or phytohaemagglutinin in neonatal rats
Abstract : The rat, as an altritial species, is born with an immature gastrointestinal tract and intestinal barrier function, which is highly absorptive to milk-borne bioactive molecules that can pass undigested and reach the general circulation of the suckling newborn. This passage occurs by the neonatal-Fc-receptor (FcRn) binding and trancytosis of immunoglobulin G in the proximal small intestine (SI) and by the highly endocytic vacuolated enterocytes non-selectively in the distal SI.
