immune system
• anti-CD3 antibody stimulated double positive T cell apoptosis is reduced in the thymus; however T and B cell development and B cell activation are normal
• anti-CD3 antibody stimulated double positive T cell apoptosis is reduced in the thymus; however T and B cell development and B cell activation are normal
• after 36 hours of culture with anti-CD3 antibody homozygous T cells produce very little IL2, IL4 or IFNG unlike wild-type cells
• reduced proliferation of splenic T cells after stimulation with anti-CD3 antibody with or without anti-CD28 antibody, especially at lower concentrations of antibodies
• however, the addition of IL2 to the culture medium increases T cell proliferation to a level similar to that of wild-type cells
