Herein, a non-classical -saccharide linkage is reported a C5 radical of pentose or C6 radical of hexose addition to Michael acceptors. C(sp)-S cleaved glycosyl thianthrenium salts are developed as the glycosyl radical agents. The reaction provides an efficient toolkit to synthesize β-glycosyl substituted unnatural amino acids as well as for the late-stage -saccharide modification of peptides.

Human leukocyte antigen class I (HLA-I) and class II (HLA-II) proteins play an essential role in epitope binding and presentation to initiate an immune response. Accurate prediction of peptide-HLA (pHLA) binding and presentation is critical for developing effective immunotherapies. However, current tools can predict antigens exclusively for pHLA-I or pHLA-II, but not both; have constraints on peptide length; and commonly show unsatisfactory predictive accuracy.

Aerobic glycolysis is a hallmark of cancer and is regulated by growth factors, protein kinases and transcription factors. However, it remains poorly understood how these components interact to regulate aerobic glycolysis coordinately. Here, we show that sine oculis homeobox 1 (SIX1) phosphorylation integrates growth factors (e.

Background: Acute lung injury (ALI) ranks among the leading reasons for death in septic patients. As an essential transcription factor associated with stress, activating transcription factor 3 (ATF3) participates in a variety of pathophysiological processes, including immunology and inflammation. However, the specific mechanism of ATF3 in pyroptosis of sepsis-induced ALI remains elusive.

The Qa-1 in mice is homologous to human leukocyte antigen E(HLA-E), and both of them belong to the non-classical major histocompatibility complex I b(MHC-I b) molecules. Qa-1 is capable of presenting self or exogenous antigen peptides to interact with two distinct receptors, namely T cell receptor (TCR) and natural killer cell group 2 member A (or C) (NKG2A/C), thus playing an important role in immune response and regulation. Qa-1-restricted regulatory CD8 T cell (CD8 Treg) is one of the most studied CD8 Treg subgroups, which can maintain immune homeostasis and autoimmune tolerance by exerting immunosuppressive effects.
