immune system

abnormal lymphopoiesis ( J:124570 )

• a mixed lymphocyte culture with alloantigen failed to proliferate

• proliferation of T cell in response to anti-CD3 alone and to the combination of anti-CD3 + anti-CD28

abnormal germinal center B cell physiology ( J:124570 )

• mutant mice sensitized and challenged with OVA fails to develop germinal centers in the spleen

• mutant animals show a normal inflammatory response to OVA stimulation

decreased immunoglobulin level ( J:124570 )

• mutant mice sensitized and challenged with OVA shows a marked decrease in OVA-specific antibody

abnormal cytokine secretion ( J:124570 )

• a substantial reduction in the amount of several cytokines in the culture supernatants of stimulated T cells

decreased interleukin-2 secretion ( J:124570 )

• reduced IL-2 present in the culture supernatants of stimulated T cells

hematopoietic system

abnormal lymphopoiesis ( J:124570 )

immune system

decreased T cell proliferation ( J:124570 , J:149888 )
