BACKGROUND Emerging evidences suggest that nucleolin expressed on the cell surface is implicated in growth of tumor cells and angiogenesis. Nucleolin is one of the major proteins of the nucleolus, but it is also expressed on the cell surface where is serves as a binding protein for variety of ligands implicated in cell proliferation, differentiation,(More)
Antimicrobial peptides (AMPs) are a diverse group of molecules that play a vital role in the innate immune response of plants and animals [1]. With an average length of thirty or so residues, AMPs often feature a net positive charge due to a high arginine, lysine and/ or histidine content. This in turn endows them with an amphiphilic character that enables(More)
The title compound, C(10)H(15)NO(4), also known as N-tert-butyl-oxycarbonyl-allohydr-oxy-l-proline lactone, is quite similar to N-acetyl-allohydr-oxy-l-proline lactone [Lenstra, Petit & Geise (1979 ▶). Cryst. Struct. Commun. 8, 1023-1029], whereby both carbonyl groups point roughly in the same direction because of the trans conformation of the peptide bond.
The immunodominant epitope of bovine type II collagen (CII256-270) in Aq mice carries a hydroxylysine-264 linked galactose (Gal-Hyl264), the recognition of which is central to the development of collagen-induced arthritis. This study explores the molecular interactions involved in the engagement of T-cell receptors (TCRs) with such epitopes. Responses of(More)
