2,3. The γδ T cell receptor (TCR), which is generated by γδ T cells, recognizes a diverse range of antigens independently of the major histocompatibility complex2. The γδ TCR associates with CD3 subunits, initiating T cell activation and holding great ...
The crystal structures of two newβ-adrenergic antagonists, derivatives of propranolol containing 2-methylalanine fragment are described in this paper. The space groups and unit-cell parameters are: compound1 (C17H21NO4): monoclinic, space groupP21/n,a=5.787(1),b=18.703(4),c=23.526(5),β=...
The σ2 receptor has attracted intense interest in cancer imaging1, psychiatric disease2, neuropathic pain3,4,5 and other areas of biology6,7. Here we determined the crystal structure of this receptor in complex with the clinical candidate roluperidone2 and the tool compound PB288. These stru...
Importantly, these FcγRs demonstrate typical murine glycosylation in the form of α-galactose epitopes, N-glycolylneuraminic acid, and other key glycan properties that are generally expressed in murine cell lines and therefore are not typically observed in humans. 展开 ...

cell culture system, airlifting, a well-documented method for promoting epithelium stratification1, was performed following the confluence of the cultivated single layer cell sheet14,15,16,17,18,19. Multilayered cell products prevented the damage of fragile cultivated cells from external stimuli after...
Three-dimensional structures of the fragile X triplet repeats (GCC)n and (GGC)n are derived by using one- dimensional/two-dimensional NMR. Under a wide range of solution conditions (10-150 mM NaCl,pH6-7)(GCC)5-7 strands form exclusively slipped hairpins with a 3' overhanging C. The sl...
