AI Article Synopsis

  • Understanding T cell function requires exploring the molecular dynamics involved in T cell activation and effector function.
  • The Jurkat (JK) CD4 T cell line serves as a valuable in vitro model for studying the intracellular signaling pathways triggered by T cell receptor (TCR) activation.
  • The text outlines protocols to assess TCR and costimulation-mediated activation, immunological synapse formation, and cytokine production, which are key processes in T cell responses across various pathophysiological contexts.

Article Abstract

In order to understand T cell function, it is necessary to completely decipher the molecular dynamics underlying T cell activation and effector function. In vitro easy-to-handle cellular models are valuable tools to study intracellular molecular mechanisms in live cells. The CD4 T cell line Jurkat (JK) has been widely employed to investigate intracellular signaling leading to T cell activation in response to T cell receptor (TCR) triggering. Here, we describe diverse, complementary protocols to evaluate the TCR- and costimulation-mediated T cell activation, as well as the immunological synapse assembly and cytokine production occurring as a consequence of successful early activation events. This in vitro model is extremely useful to address molecular mechanisms operating during T cell activation and effector function acting in diverse pathophysiological scenarios.

Mechanistic target of rapamycin complex 1 (mTorC1) activity plays a crucial role in brain development. Here, we present an approach for rapamycin microinjection into the habenula of larval zebrafish to achieve localized inhibition of the mTorC1 pathway and explore the role of mTorC1 in habenula function. We describe steps for performing microinjections and maintaining zebrafish larvae before and after the procedure.

Ergosterol alleviates hepatic steatosis and insulin resistance via promoting fatty acid β-oxidation by activating mitochondrial ACSL1.

Sterols target sterol-sensing domain (SSD) proteins to lower cholesterol and circulating and hepatic triglyceride levels, but the mechanism remains unclear. In this study, we identify acyl-coenzyme A (CoA) synthetase long-chain family member 1 (ACSL1) as a direct target of ergosterol (ES). The C-terminal domain of ACSL1 undergoes conformational changes from closed to open, and ES may target the drug-binding pocket in the acetyl-CoA synthetase-like domain 1 (ASLD1) of ACSL1 to stabilize the closed conformation and maintain its activity.

Polycomb repressive complex 2 (PRC2), composed of the core subunits EED, SUZ12, and either EZH1 or EZH2, is critical for maintaining cellular identity in multicellular organisms. PRC2 deposits H3K27me3, which is thought to recruit the canonical form of PRC1 (cPRC1) to promote gene repression. Here, we show that EZH1-PRC2 and cPRC1 are the primary Polycomb complexes on target genes in non-dividing, quiescent cells.

Interleukin (IL)-7 promotes T cell expansion during lymphopenia. We studied the metabolic basis in CD4 T cells, observing increased glucose usage for nucleotide synthesis and oxidation in the tricarboxylic acid (TCA) cycle. Unlike other TCA metabolites, glucose-derived citrate does not accumulate upon IL-7 exposure, indicating diversion into other processes.

Cadmium (Cd) is a toxic heavy metal which induces vascular disorders. Previous studies suggest that Cd in the bloodstream affects vascular endothelial cells (ECs), potentially contributing to vascular-related diseases. However, the molecular mechanisms of effects of Cd on ECs remain poorly understood.
