HDAC3 has been demonstrated to play a crucial role in the progression of various tumors and the differentiation and development of T cells. However, its impact on peripheral T cells in the development of murine lung cancer remains unclear. In this experiment, a subcutaneous lung tumor model was established in C57BL/6 mice, and tumor-bearing mice were treated with the specific inhibitor of HDAC3, RGFP966, at different doses to observe changes in tumor size.

Pyroptosis, also known as inflammatory necrosis, is a form of programmed cell death characterized by the activation of gasdermin proteins, leading to the formation of pores in the cell membrane, continuous cell swelling, and eventual membrane rupture. This process results in the release of intracellular contents, including pro-inflammatory cytokines like IL-1β and IL-18, which subsequently trigger a robust inflammatory response. This process is a crucial component of the body's innate immune response and plays a significant role in combating infections.

Central nervous system (CNS) resident memory CD8 T cells (T) that express IFN-γ contribute to neurodegenerative processes, including synapse loss, leading to memory impairment. Here, we show that CCR2 signaling in CD8 T that persist within the hippocampus after recovery from CNS infection with West Nile virus (WNV) significantly prevents the development of memory impairments. Using CCR2-deficient mice, we determined that CCR2 expression is not essential for CNS T cell recruitment or virologic control during acute WNV infection.

Immune checkpoint inhibitors, especially those targeting CD274/PD-L1yield powerful clinical therapeutic efficacy. Thoughmuch progress has been made in the development of antibody-basedCD274 drugs, chemical compounds applied for CD274degradation remain largely unavailable. Herein,baicalein, a monomer of traditional Chinese medicine, isscreened and validated to target CD274 and induces itsmacroautophagic/autophagic degradation.

Lung adenocarcinoma (LUAD) stands out as a prevalent malignant tumor necessitating innovative strategies to enhance therapeutic outcomes. Akkermansia muciniphila (AKK) has emerged as intricately linked to tumor immunotherapy, yet its impact on natural killer (NK) cells, which play a crucial role in immunotherapy, remains unclear. This study aims to investigate the effects of AKK outer membrane proteins on NK cells in LUAD and elucidate potential associated molecular mechanisms.
