andMYD88mutations are frequently and simultaneously detected in B cell malignancies. It is not known if these mutations cooperate or how crosstalk occurs. Here we analyze the consequences ofCD79BandMYD88L265Pmutations individually and combined in normal activated mouse B lymphocytes.CD79Bmutations alone increased surface IgM but did not enhance B cell survival, proliferation, or altered NF-κB responsive markers. Conversely, B cells expressingMYD88L265Pdecreased surface IgM coupled with...[Show more]
