Neutrophil Extracellular Trap (NET) is a mechanism by which bacteria and other pathogenic organisms are rendered trapped in a site of inflammation.  An activated Neutrophil extrudes it own genomic DNA, rich with histones and other proteins, to trap invading pathogenic organisms.  However, in SLE patients, a distinct subset of Neutrophils, Low Density Granulocytes (LDGs) are […]

This is distinct from recruitment of Th1 cells where CD162 is also necessary for rolling.  CD43 mediated adhesion could provide a means to selectively manipulate Th17 immune response. “CD43 Functions as an E-Selectin Ligand for Th17 Cells in Vitro and Is Required for Rolling on the Vascular Endothelium and Th17 Cell Recruitment during Inflammation In

These effects are Treg and IL-4 independent, and are instead dependant on the helminth specific Th2-mediated Eosinophilia in which IL-5 and IL-33 cytokines are crucial. “Helminth Products Protect against Autoimmunity via Innate Type 2 Cytokines IL-5 and IL-33, Which Promote Eosinophilia.”   Conor M Finlay, Kingston H.G.

Despite the pronounced proliferative effect of recombinant pentameric GITRL on T cells, MC38 adenocarcinoma tumor failed to regress due to suppressive effect of accumulating Treg  in tumor tissue and draining lymph node. “Authentic GITR Signaling Fails to Induce Tumor Regression unless Foxp3+ Regulatory T Ccells Are Depleted” Y.H.

This Danish research group used a cocktail of Ancell Biotinylated anti tetraspan antibodies, anti-CD9, anti-CD63 and anti-CD81 to detect microvesicles captured on EV microarray.  The ability to characterize plasma derived exosomes in a high throughput manner may be very helpful in diagnosing cancer prognosis. “Potentials and capabilities of the Extracellular Vesicle (EV) Array” Malene Mǿller

Internalized ApoD is colocalized in intracellular vesicular compartments with CD147.  Downregulation of CD147 results in lower ApoD internalization.  Induction of CD147 overexpression resulted in increased ApoD internalization.  CD147 is a putative receptor for ApoD. “Apolipoprotein D Internalization Is a Basigin-dependent Mechanism” Ouafa Najyb, Louise Brissette, Eric Rassart (June 2015) J Biol Chem 290: 16077-16087.

This group demonstrated that physiologic levels of HDL act as an effective opsonin, facilitating uptake of M41-type Group A Streptococcus by human monocyte cell line U-937.  Pre incubation with anti-CD36 antibody (clone SM0) completely blocked this phagocytosis. “High-density lipoprotein acts as an opsonin to enhance phagocytosis of group A streptococcus by U937 cells.” Ling Liu,
