Summary: In the development of aGVHD, gamma delta T cells were found to indirectly regulate the migration of CD4 T cells to target tissues, rather than directly triggering alloreactive responses. This study suggests a potential role for gamma delta T cells in recruiting alloreactive CD4 T cells through the expression of CXCR4, providing new insights into the mechanism of aGVHD and potential therapeutic targets.

Summary: The study found that phenotypic alterations of circulating V delta 2(+) gamma delta T cells in peripheral blood of breast cancer patients were already established at diagnosis and related to tumor progression. Terminally differentiated V delta 2(+) gamma delta T cells expressing markers of senescence and exhaustion were significantly associated with lymph node invasion. This supports the involvement of V delta 2(+) gamma delta T cells in breast cancer pathogenesis and progression, highlighting the potential of liquid biopsies to monitor tumor-infiltrating immune cells.

Summary: Triptolide can activate iNKT cells in the liver, leading to liver injury. Hepatic cDCs exhibit immunogenic activities after TP administration and activate iNKT cells through IL-12, causing liver damage. TP activates the STING signaling pathway and induces ER stress, promoting the activation of cDCs and iNKT cells, resulting in hepatotoxicity.

Summary: This study found that γδ T cells play an important role in post-infectious irritable bowel syndrome (PI-IBS) through the regulation of adenosine 2A receptor (A2AR). The PI-IBS mouse model showed increased ATP content and A2AR expression, and inhibition of A2AR worsened the clinical characteristics of PI-IBS. In vitro and in vivo experiments revealed that γδ T cells express A2AR and produce IL-1, IL-6, IL-17A, and IFN-a in PI-IBS, which can be controlled by A2AR agonist and antagonist. Mechanistic studies demonstrated that A2AR antagonist improved the function of γδ T cells through the PKA/CREB/NF-κB signaling pathway.

Summary: Signaling analysis of nonlinear channel and links is challenging due to the absence of linear time-invariant principles. This work proposes a fast and accurate method for analyzing large-scale nonlinear circuits with jitter effect. By performing O(k) nonlinear simulations, the characteristic responses of the circuit can be obtained, leading to efficient evaluation of worst-case eye and bit error rate (BER).

Summary: The immune microenvironment in breast cancer is regulated by cancer cell-derived extracellular vesicles, which control the recruitment and accumulation of B lymphocytes. The Liver X receptor (LXR)-dependent transcriptional network and the tetraspanin 6 (Tspan6) play key roles in this process by regulating the accumulation of oxysterol ligands in extracellular vesicles.

Summary: Researchers have designed pan-coronavirus antivirals that target conserved viral components, and have identified H84T-BanLec as a potential inhibitor of Middle East respiratory syndrome coronavirus (MERS-CoV), severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (including Omicron), and other human-pathogenic coronaviruses. H84T-BanLec exhibits potent antiviral activity at nanomolar concentrations and protects against MERS-CoV and SARS-CoV-2 infection in vivo. Mechanistic assays reveal that H84T-BanLec targets virus entry by binding to high-mannose glycans on the viral spike protein, competing with SARS-CoV-2 spike for binding to cellular ACE2. This drug compound's broad-spectrum antiviral activity is attributed to its multiple binding sites on the spike protein, which likely prevents the emergence of resistant mutants.
