we have previously shown that mab ly-5 which on b cells recognizes a 220,000-da ( b220 ) molecule , inhibits lps-induced igg responses without affecting igm or proliferative responses , whereas mab lyb-2 which modulates b cell activation processes induced by b cell stimulatory factor-1 ( bsf-1 ) or il-4 , has no effect on lps-induced b cell responses .
