ER stress and its PERK branch enhance TCR-induced activation in regulatory T cells.

Biochem Biophys Res Commun 2021 Jul 28;563:8-14. Epub 2021 May 28.

Department of Microbiology and Immunology, Trauma Research Center, Fourth Medical Center of the Chinese PLA General Hospital, Beijing, PR China. Electronic address:

Although accumulating evidence indicates participation of endoplasmic reticulum (ER) stress pathway or the unfolded protein response (UPR) in immunity, there still exists little information linking ER stress to regulatory T cells (Tregs). To evaluate the potential contribution of the UPR, we tested the effects of thapsigargin (TG), an ER stress inducer, on the function of Tregs. Here we reported that TG stimulation induced the up-regulation of the endoplasmic reticulum (ER)-stress chaperon Glucose-Regulated Protein 78 (GRP78), which is a master regulator of the UPR, the phosphorylation of eukaryotic initiation factor 2 alpha (elF2α) and the induction of activating transcription factor 4 (ATF4), which are both protein kinase R (PKR)-like ER kinase (PERK) downstream targets in Tregs.

Quantifying Frustrations for Molecular Complexes with Noncovalent Interactions.

J Phys Chem A 2021 Jun 30;125(22):4910-4917. Epub 2021 May 30.

Key Laboratory of Chemical Biology and Traditional Chinese Medicine Research (Ministry of Education of China), and College of Chemistry and Chemical Engineering, Hunan Normal University, Changsha, Hunan 410081, P. R. China.

Molecular systems bound together through noncovalent interactions are involved in a lot of life-essential processes such as molecular recognition, signal transduction, and allosteric regulation. While cooperation as an important effect discovered in these systems focuses on the behavior of system's entirety, we need also examine the behavior of individual parts. In this work, using the distortion energy as the descriptor, we quantify frustration as the energetic loss of individual parts due to the formation of nonadditive molecular complexes. Read More
