This observation suggests that blocking engagement of CD134 with its ligand is responsible for this effect.
More importantly, we could substantially reconstitute the cross-priming capacity of DCs that had engulfed infected neutrophils by using antibodies to block engagement of Mer, or by using bone marrow-derived DCs prepared from Mer−/− mice.
CCR5 is the primary chemokine receptor utilized by HIV to infect leukocytes, whereas CCR5 ligands inhibit infection by blocking CCR5 engagement with HIV gp120.
This well characterized mAb has been extensively used to block CD40 engagement by CD40L expressing cells.
EN-RAGE also decreased NF-κB activation and pro-inflammatory cytokine expression by blocking RAGE engagement.
Murine sFasL is reported to be non-apoptotic and anti-inflammatory, and can even act as an antagonist by blocking mFasL engagement with the Fas receptor.
Once on vesicles, additional Rab6A binding to the motor domain binding may regulate the load that other motors on the vesicle experience, by blocking KIF1C engagement with microtubules.
However, the competitive binding inhibition did not completely block the engagement of BECN1 to AMBRA1 even with excessive overexpression of WASH.
The agent, which binds to CD80 and CD86 on antigen-presenting cells, blocking the engagement of CD28 on T cells and thus preventing T cell activation, acts earlier in the inflammatory cascade than do other biologic therapies by directly inhibiting the activation of T cells and the secondary activation of macrophages and B cells.
Their obligatory role in RA synovitis was recently proved by successful treatment of active disease by selective inhibition of T-cell activation with fusion protein of cytotoxic T-cell-associated antigen 4 (CD152 -IgG, which can block the engagement of CD28 on T cells by binding to CD80 and CD86 with high avidity [ 23].
