Abstract Previously, we reported that a peptide, p458, from the sequence of mammalian 60-kDa heat shock protein (hsp60) molecule can serve as carrier in conjugate vaccines with capsular polysaccharide (CPS) molecules various bacteria. These were effective injected PBS without added adjuvants. We now report p458 conjugated to pneumococcal CPS type 4 (PS4) manifests innate adjuvant effects: it stimulated mouse macrophages secrete IL-12 and induced late appearance PS4 on macrophage surface...
Recent advances in the field of cell therapy have proposed new solutions for tissue repair and regeneration using various delivery approaches. Here we studied ex vivo a novel topical system encapsulated cells hybrid polyethylene glycol-fibrinogen (PEG-Fb) hydrogel microspheres to respiratory tract models. We investigated basic parameters encapsulation, release conditions inflamed damaged lungs bacterial-infected mice. The establishment each step study was essential proof concept....
HIV infection is initiated by the fusion of viral membrane with target T-cell membrane. The envelope glycoprotein, gp41, contains a peptide (FP) in N terminus that functions together other gp41 domains to fuse virion host cell We recently reported FP co-localizes CD4 and receptor (TCR) molecules, co-precipitates TCR, inhibits antigen-specific proliferation pro-inflammatory cytokine secretion. Molecular dynamic simulation implicated an interaction between α-helical transmembrane domain (TM)...
The COVID-19 pandemic has led to high global demand for vaccines safeguard public health. To that end, our institute developed a recombinant viral vector vaccine utilizing modified vesicular stomatitis virus (VSV) construct, wherein the G protein of VSV is replaced with spike SARS-CoV-2 (rVSV-ΔG-spike). Previous studies have demonstrated production VSV-based in Vero cells adsorbed on Cytodex 1 microcarriers or suspension. However, titers were limited by both carrier surface area and shear...
Mice are exceedingly sensitive to intra-peritoneal (IP) challenge with some virulent pneumococci (LD50 = 1 bacterium). To investigate how peripheral contact bacterial capsular polysaccharide (PS) antigen can induce resistance, we pulsed bone marrow dendritic cells (BMDC) of C57BL/6 mice type 4 or 3 PS, injected the BMDC intra-foot pad (IFP) and challenged IP supra-lethal doses pneumococci. We examined responses T B in draining popliteal lymph node measured effects on bacteria peritoneum...
The intestine is lined with isolated lymphoid follicles (ILFs) that facilitate sampling of luminal antigens to elicit immune responses. Technical challenges related the scarcity and small sizes ILFs their follicle-associated epithelium (FAE) impeded characterization spatial gene expression programs. Here, we combined RNA sequencing laser capture microdissected tissues single-molecule transcript imaging obtain a map ILF its associated FAE in mouse intestine. We identified zonated programs...
Abstract Constant exposure of intestinal epithelial cells (IEC) to potentially damaging stimuli makes mucosal repair programs essential for gut homeostasis, immunological quiescence and resistance colitis. Trefoil factor 2 (TFF2) is a mucus associated protein that promotes barrier integrity in the lung intestine, but whether bona-fide TFF2 receptor exists remains controversial. Herein, we provide evidence leucine rich repeat nogo interacting 3 (LINGO3) transmembrane component signaling...
