Summary: Peripheral T lymphocyte proliferation is partly dependent on their thymic developmental history. The rate of proliferation of T cells with different TRB rearrangement status is different in men and women before the age of 18, but similar thereafter. Over time, T cell clone size becomes more heterogeneous, and in adults, it is always more even in women. A longitudinal analysis of TRB repertoires obtained at ten-year intervals from individual men and women confirms the findings of this cross-sectional study.

Summary: The peripheral T cell pool is maintained through thymic output and self-renewal of naive T cells. Loss of RPA1 leads to lymphopenia, limited TCR repertoire diversity and increased susceptibility to inflammatory diseases. Mechanistically, RPA1 deficiency triggers genomic DNA leakage, activates ZBP1-RIPK3 signaling, and induces necroptotic T cell death and release of DAMPs, contributing to inflammation.

Summary: During NAFLD progression, TCR gamma delta+ DNT cells enhance IL17A secretion and aggravate liver inflammation, whereas TCR alpha beta(+) DNT cells decrease GZMB production and lead to weakened immunoregulatory function. Shifting of balance from TCR gamma delta+ DNT cell response to one that favors TCR alpha beta(+) DNT regulation would be beneficial for the prevention and treatment of NAFLD.

Summary: DLG1 plays a crucial role in regulating T cell activation by promoting TCR-MC formation even before immunological synapse formation. Additionally, DLG1 acts as a bridge between TCR-ζ chain and ZAP70 while inhibiting the binding of phosphatase SHP1 to TCR-ζ. These effects ultimately lead to dysregulation of T cell activation in DLG1-deficient T cells, impacting vaccine response strategies.

Summary: In this research, a nucleic acid nanoassembly (NAN)-based technology was developed for functionalization of hydrogels to efficiently capture human T lymphocytes and activate TCR. The platform allows for regulation of 3D force momentum and 2D shear modulus, providing new tools to address the mechanical stimulation issue during the initial phase of immune surveillance.

Summary: The study found that most hyper-expanded CDR3 are individual-specific, with TRBV3-1 gene usage more frequent in the tumor group, and identified 374 hyper-expanded tumor-specific CDR3 which may play a vital role in anti-tumor immune responses. Patients with stage IV gastric cancer have higher EBV-specific CDR3 abundance.

Summary: Zinc, an essential microelement, plays immunoregulatory roles by influencing signaling pathways to enhance immune function. Zinc deficiency impairs immunity and increases susceptibility to infection. The interaction between Zip6-mediated zinc influx and TCR activation regulates T-cell responses.

Summary: The existence of mRNA m6A modification has long been known, but its regulatory potential has only recently been discovered. Current research focuses on the molecular determinants and consequences of this modification, as well as its importance for specific cell types and programs. This review summarizes the current knowledge on m6A modification in T cells and its impact on T cell activation.

Summary: THEMIS has been identified as a crucial regulator in T cell development and recent studies indicate that it stimulates TCR-mediated signaling by suppressing the activity of tyrosine phosphatases SHP-1 and SHP-2, thereby influencing T cell activation. In addition to its role in thymic selection, THEMIS also plays a significant role in peripheral T cell function.

Summary: During the late phase of infection, Leishmania donovani exploits the antiapoptotic protein myeloid cell leukemia-1 (MCL-1) and its binding partner translationally controlled tumor protein (TCTP) to protect its niche and establish infection. The steady translational level of MCL-1 up to 48 hours postinfection and the increased phosphorylation of TCTP in infected macrophages suggest their importance in the late hours of infection. Knockdown of TCTP decreases MCL-1 expression and reduces parasite burden, inducing liver cell apoptosis in an infected mouse model.

Summary: A nationwide study in Taiwan using the National Health Insurance Research Database from 1997 to 2013 found that patients with atopic dermatitis (AD) have a higher risk of fractures, especially in severe cases of AD. Additionally, patients exposed to topical or systemic corticosteroids have an increased risk of fractures, while the use of disease-modifying antirheumatic drugs and phototherapy is associated with a lower risk of fractures.

Summary: MTTP is essential for assembling and secreting triglyceride-rich lipoproteins, and a newly identified protein PRAP1 plays a key role in MTTP-mediated lipid transport. PRAP1 binds to triglycerides and facilitates lipid transfer alongside MTTP. Deficiency or mutation of PRAP1 leads to challenges in lipid absorption, but reduces body weight and fat mass on high-fat diets.
