Although extranuclear histones have been identified for a long time, their role in lymphocytes, particularly cytoplasmic histones, remains elusive. In this study, we conducted a visual and quantitative analysis of cytoplasmic histones in CD4 T cells and discovered that effector CD4 T cells contain higher levels of cytoplasmic histones compared to naïve T cells. We observed a significant increase in cytoplasmic histones following T cell receptor (TCR) activation, with further elevation during the differentiation of Th1 and Th17 cells.

Compared with clean fuels(electric, liquefied petroleum gas, natural gas, marsh gas and solar), solid fuels can cause numerous health hazards. There is limited evidence suggesting that the use of solid fuel is associated with self-perceived low back pain (LBP) and neck pain (NP).

Migrant older adults (MOAs) may experience physical and psychological discomfort in influx cities, and they are a vulnerable group that has emerged in the course of fast urbanization. Previous studies have confirmed the association between oral health and loneliness as well as the relationship between social support and loneliness; however, no research has been done to clarify the underlying mechanisms and the migrant-local difference between oral health, social support, and loneliness.

Objective: Existing research has yet to adequately examine the correlation between sleep time, body pain, and depressive symptoms. This study seeks to elucidate the interconnections between these three elements.
Methods: The study used 2020 CHARLS data for analysis.
An increasing number of expression quantitative trait loci (eQTLs) have been linked to tumorigenesis. In this study, we used Mendelian randomization (MR) to identify a novel cancer susceptibility gene, Trimethylguanosine Synthase 1 (TGS1). TGS1-induced hypermethylation at the 5' end of human telomerase RNA (hTR) impedes hTR accumulation, decreasing telomerase assembly factor levels and thus limiting telomere elongation, a crucial factor in tumor progression.

Background: Dysfunction of CD8 T cells in the tumor microenvironment (TME) contributes to tumor immune escape and immunotherapy tolerance. The effects of hormones such as leptin, steroid hormones, and glucocorticoids on T cell function have been reported previously. However, the mechanism underlying thyroid-stimulating hormone (TSH)/thyroid-stimulating hormone receptor (TSHR) signaling in CD8 T cell exhaustion and tumor immune evasion remain poorly understood.

Here, we show that energy stress promotes the formation of P-bodies in a ubiquitin-dependent manner. Upon ATP depletion, the E3 ubiquitin ligase TRIM23 catalyzes lysine-63 (K63)-linked polyubiquitination of HCLS1-associated protein X-1 (HAX1).

Carolacton, a naturally occurring MTHFD1 inhibitor, exhibits potent inhibitory activity against various RNA viruses including SARS-CoV-2. Herein, we present a concise total synthesis of carolacton, featuring the Krische allylation, Marshall coupling, NHK coupling, and RCM reaction as key elements. Additionally, we have synthesized three simplified carolacton analogues, one of which, namely, 14-demethyl-carolacton, exhibited notable antiviral activity.
