Polymorphonuclear leukocyte regulation of lymphocyte proliferation and differentiation.

abstract：:Guinea pig (gp) platelets react to nanomolar doses of the complement-derived anaphylatoxin C5a with a shape change, aggregation and release of biogenic amines and nucleotides from their granules. We have investigated the specific receptor for C5a on gp platelets which mediates these biological effects. Competitive bin...

abstract：:Details of the "Trojan Horse" mechanism by which Zika virus (ZIKV) crosses the blood-brain barrier (BBB) remain unclear. However, the migration of ZIKV-infected monocytes to the brain is thought to be dependent on both pattern-recognition and chemokine receptors. In this study, we investigated whether the migration of...
