Statement of Purpose: Hyaluronic acid (HA) is a biodegradable, biocompatible, non-immunogenic, nontoxic, and non-inflammatory linear polysaccharide. HA has been used for various medical applications such as arthritis treatment, ocular surgery, tissue augmentation, drug delivery and tissue engineering [1]. In this work, HA has been extensively investigated as novel drug carriers for target speci...

Just as potentially useful T cells are positively selected by MHC-peptide complexes in the thymus, it has been proposed that self or commensal bacterial epitopes might select B cell populations with the capacity to recognize polysaccharide or protein structures on pathogens. Recent studies indicate that the repertoire of B cells entering the periphery is not shaped by specific stimuli, but that...

A crude polysaccharide-protein complex from Lactarius deliciosus fruit bodies (LDP) was extracted with hot water, precipitated, and washed with 95% ethanol. After protein removal according to the Sevag method, LDP was dialyzed against running tap water and distilled water, and further purified by Sephadex G-100 column chromatography. Gas chromatography showed that LDP is composed of glucose, ga...

milk proteins provide a natural source of bioactive peptides with potential health benefits and applications in the food industry. the release of these peptides from milk proteins is achieved either by hydrolysis using digestive proteases or by lactic acid bacteria fermentation. peptides, particularly those derived from milk proteins, can exert a wide range of nutritional, functional and biolog...

The extracellular matrix (ECM) of Volvox contains insoluble fibrous layers that surround individual cells at a distance to form contiguous cellular compartments. Using immunological techniques, we identified a sulfated surface glycoprotein (SSG 185) as the monomeric precursor of this substructure within the ECM. The primary structure of the SSG 185 poly-peptide chain has been derived from cDNA ...

Healthy persons manifest a high frequency of T cells reactive to epitopes of the self 60-kDa heat-shock protein (hsp60) molecule. It was reasoned that a self hsp60 peptide, p458m, might provide T cell help for a response to the T independent capsular polysaccharide of Streptococcus pneumoniae type 4 (PS4). The conjugate vaccine (PS4-p458m) induced resistance to challenge with >300,000 times the...

Ganoderma lucidum is a white-rot fungus that has been viewed as a traditional Chinese tonic for promoting health and longevity. It has been revealed that several extractions from Ganoderma lucidum, such as Ethanol extract, aqueous extract, mycelia extract, water soluble extract of the culture medium of Ganoderma lucidum mycelia, Ganodermasides A, B, C, D, and some bioactive components of Ganode...

The Ganoderma lucidum (G. lucidum) mushroom is one of the most extensively studied functional foods, known for its numerous health benefits, including the inhibition of tumor cell growth. The present study assessed the anti-proliferative and pro-apoptotic activity of a novel G. lucidum polysaccharide peptide (GL-PP) in human glioma U251 cells, which was purified from grass-cultured G. lucidum. ...
