Although the accumulation of amyloidogenic proteins in neuroinflammatory conditions is generally considered pathologic, in a murine model of multiple sclerosis, amyloid-forming fibrils, comprised of hexapeptides, are anti-inflammatory. Whether these molecules modulate systemic inflammatory
Amyloid fibrils composed of peptides as short as six amino acids are effective therapeutics for experimental autoimmune encephalomyelitis (EAE). Immunosuppression arises from at least two pathways: (1) expression of type 1 IFN by pDCs, which were induced by neutrophil extracellular traps arising
Retroviral infections are frequently associated with immunosuppression. Retroviral transmembrane envelope proteins (TM proteins) play an important role in this phenomenon. CKS-17, a synthetic heptadecapeptide, represents the immunosuppressive site of these retroviral TM proteins. Here we support on
Guinea pig peritoneal macrophages were examined for their response to homologous anaphylatoxic peptide C3a of complement. C3a caused the release of considerable amounts of thromboxane A2 from macrophages maintained in serum-free culture for up to 12 hr. Preincubation of C3a with the Fab portion of a
In a ProteoChip‑based screening system and subsequent studies, serine‑aspartic acid‑valine (SDV) was demonstrated to specifically bind to integrin αvβ3. An SDV‑containing peptide could target the tumor vessel and it may be an effective replacement for molecular imaging of the tumor. In the present
The visceral mass of the gastropod, Harpa ventricosa was hydrolysed using trypsin, alcalase and pepsin for 12 h to produce protein hydrolysates. Subsequently, the active hydrolysate was observed in the 3rd hour of tryptic hydrolysate (29.17 ± 0.62 and 34.85 ± 0.55 %) using human red blood cell
The membrane lipoproteins of Treponema pallidum and Borrelia burgdorferi have potent immunostimulatory properties in vitro, implicating them as major inflammatory mediators in syphilis and Lyme disease. Recently, we reported that synthetic lipohexapeptide analogs (lipopeptides) of the lipoproteins
OBJECTIVE
Adventitia acts as an active participant in vascular inflammation but the precise mechanism underlying adventitia-mediated vascular inflammation is not fully understood. In this study, we sought to determine whether vascular endothelial growth factor (VEGF) regulates osteopontin (OPN)
OBJECTIVE
To investigate the direct effects of placenta growth factor (PlGF) and its specific receptor, flt-1, which are known to mediate angiogenesis, on the inflammatory process of rheumatoid arthritis (RA).
METHODS
Expression of PlGF and flt-1 in the synovial tissue of RA patients was examined
Over 1 million cases of scorpion stings are estimated every year, whereas current treatment is limited to antivenom serum combined with supportive therapy. Tityus serrulatus scorpion venom (TsV) is composed of diverse molecules, including toxins that induce a catecholamine storm and mediate
Psoriasis is one of the most prevalent chronic inflammatory diseases of the skin. The Wnt pathways have been documented to play essential role in stem cell self-renewal and keratinocyte differentiation in the skin. Antagonizing the Wnt5a protein would emerge as a novel therapeutics in psoriasis
BACKGROUND
Pre-treatment of plasma with hexapeptide ligand libraries prior to proteomic analysis is well documented. However, the maintenance of biomarker abundance throughout the different pre-analytical steps is required for a potential application of differential proteomics in clinical
Tumour necrosis factor alpha (TNF-alpha) is a pro-inflammatory cytokine with pleiotropic activity that binds to two transmembrane receptors. Its role in mediating the inflammatory response to injury or infection has been well documented and it has been shown to be a causative factor in rheumatoid
The authors examined the human blood mononuclear-induced tumor necrosis factor production using the new drug--the synthetic hexapeptide Immunophan. The levels of tumor necrosis factor in the supernatant liquid were measured by the enzyme immunoassay and the cytotoxic test using L-929 fibroblastoid
A hexapeptide, Ac-RRWWCR-NH(2) (Antileukinate), has been reported to be a potent inhibitor of CXC-chemokine receptor. However, the in vivo anti-inflammatory activity of this agent has not been tested except in a rabbit skin edema model. This study was undertaken to investigate the effect of
