immune system
• levels of memory T cells, based on CD62L and CD44 expression, are decreased by about 50%
|
• T cells display defective cytokine responses to CD28-dependent costimulatory signals
• colligation of CD3/CD28 does not enhance progression of T cells into G2/M as observed in wild-type T cells
|
• T cells show defective proliferative responses to CD28-dependent costimulatory signals in vitro
• in vitro proliferative response of T cells to CD3/CD28 coligation is reduced by more than 80%
• in vivo proliferative response of T cells to the superantigen staphylococcal enterotoxin A (SEA) is reduced by about 60%
|
• T cells display impaired memory responses to proteolipid protein peptide (PLP)
|
• T cells display reduced IL-2 production in response to CD28 ligation
|
• mutants do not develop proteolipid protein peptide (PLP)-induced experimental autoimmune encephalomyelitis
