CD86 regulates myeloma cell survival.
Although prognosis for patients with multiple myeloma has improved over the past decade, research toward discovery of new therapeutic avenues is important and could lead to a cure for this plasma cell malignancy. Here we show that blocking the CD28-CD86 pathway via silencing of either CD28 or CD86 leads to myeloma cell death. Inhibiting this pathway leads to downregulation of integrins and IRF4...
متن کاملCD80/CD86 costimulation regulates acute vascular rejection.
Xenotransplantation may provide the only solution to the shortage of human donor organs. Although hyperacute rejection associated with xenotransplantation can now be overcome, acute vascular rejection (AVR) remains a primary barrier to xenotransplantation. To date, standard immunosuppressive agents fail to block AVR or prolong xenograft survival. The present study was undertaken to determine th...
متن کاملGata1 regulates dendritic-cell development and survival.
Dendritic cells are key initiators and regulators of the immune response. Dendritic cell commitment and function require orchestrated regulation of transcription. Gata1 is a transcription factor expressed in several hematopoietic lineages. However, Gata1 function has not been explored in the monocytic or dendritic cell compartment. Here, we show that Gata1 is expressed in myeloid and plasmacyto...
متن کاملCD86 regulates IgG1 production via a CD19-dependent mechanism.
CD86 signals directly in a B cell to activate PI3K and increase the rate of IgG(1) production, without affecting germline transcription. However, the mechanism by which CD86 activates PI3K in a B cell and the relevance of CD86 stimulation in vivo remains unknown. We show that the addition of CD28/Ig to CD40 ligand/IL-4-activated wild-type, but not CD86- or CD19-deficient, B cells increased the ...
متن کاملThe KDM3A–KLF2–IRF4 axis maintains myeloma cell survival
KDM3A is implicated in tumorigenesis; however, its biological role in multiple myeloma (MM) has not been elucidated. Here we identify KDM3A-KLF2-IRF4 axis dependence in MM. Knockdown of KDM3A is toxic to MM cells in vitro and in vivo. KDM3A maintains expression of KLF2 and IRF4 through H3K9 demethylation, and knockdown of KLF2 triggers apoptosis. Moreover, KLF2 directly activates IRF4 and IRF4 ...
