Summary: This research found that PD-1 expression on T cells increased in mice with chronic graft-versus-host disease (cGVHD). Intervention of the PD-1/PD-L1 pathway showed a significant impact on the occurrence of cGVHD and graft-versus-tumor effect.

Summary: After HSCT, the response of T cell subsets to exogenous IL-2 depends on the host's immune environment, with implications for the balance of GVHD and GVL.

Summary: Although T cells producing interleukin-22 (IL-22) in breast and lung tumors are associated with poor patient outcomes, deletion of IL-22 or its receptor reduces metastasis in mouse models. IL-22 induces high expression of CD155, which impairs the function of NK cells and increases metastatic burden. The findings suggest an immunosuppressive circuit activated by T cell-derived IL-22 that promotes lung metastasis.

Summary: The involvement of IL-17A in immune-mediated hepatitis was investigated using a mice model with intestine exposed to Salmonella typhimurium. The study found that IL-17A overactivation of NKT cells contributed to severe liver injury in Con A-induced immune-mediated hepatitis. Additionally, MAIT-cell-derived IL-17A was identified as the original driver of NKT cell overactivation. This axis could potentially serve as a therapeutic target in autoimmune liver disease.

Summary: Our study demonstrated that IL-22 overexpression in LN activated the STAT3 signaling pathway, increased chemokine secretion, promoted macrophage infiltration, and thus aggravated LN in lupus-prone mice. This suggests that IL-22 may play a pathogenic role in LN and serve as a potential therapeutic target for LN.

Summary: We explored the use of IL-21 cell-based anti-leukemia treatment in a mouse model of acute lymphoblastic leukemia. Injection of IL-21-secreting 70Z/3 leukemia cells induced a strong anti-leukemia response and led to 100% survival rate. IL-21 secretion correlated with improved survival and the expansion of IL-21-secreting cells. The delivery of IL-21 showed the potential to induce a potent immune response and long-term immunity, making it an attractive candidate for cancer immunotherapy.

Summary: Cytotoxic CD4(+) T cells play important roles in both cancer and non-cancer environments, where they can directly kill cancer cells. They are also found in situations like infection and autoimmunity. The cytolytic mechanisms of cytotoxic CD4(+) T cells vary across different disease states.

Summary: The study reveals that S100A4 drives dysfunction in CD8(+) T-EM cells, leading to the loss of their protective memory response and promoting asthma worsening. CD8(+) T-EM cells can be divided into dysfunctional subsets and subsets inclined towards apoptosis based on the expression of S100A4. S100A4 affects mitochondrial metabolism, leading to a decrease in acetyl-CoA levels, which impairs the transcription of effector genes (especially IFN-γ), facilitating cell survival, tolerance, and memory potential.

Summary: IL-26 is a newly discovered member of the IL-10 cytokine family mainly secreted by Th17 cells, and its involvement in malignant pleural effusion (MPE) production and promotion has been reported for the first time in this study. Elevated levels of IL-26, IL-10, and IL-6 were observed in MPE compared to peripheral blood, with the primary cell source of IL-26 being Th17 cells. Additionally, IL-26 was found to impact the proportions of CD4(+) T cells and CD8(+) T cells, influencing their tumor-killing activity and patient survival.

Summary: Lack of IKK1 in CD4(+)T lymphocytes reduces renal injury caused by IRI by decreasing the ability of CD4 lymphocytes to differentiate into Th1/Th17 cells. This finding suggests that targeting IKK1 in lymphocytes may be a novel therapeutic strategy for IRI.

Summary: This study built a computational model to simulate the complex mechanisms of immune and metabolic regulation of CD4+ T cell functions. The model revealed how CD4+ T cells shape the immune response during Clostridioides difficile infection (CDI) and the potential pharmacological targeting to enhance regulatory (Treg) response. Activation of LANCL2 decreased effector response, increased regulatory response, and induced metabolic changes favoring Treg development. Gluconeogenesis via PEPCK-M was identified as a potential factor responsible for increased immunosuppressive behavior in Treg cells.

Summary: Research suggests that the upregulation of alpha 4 beta 7 integrin, CD162E, CD162P, and downregulation of CD62L on peripheral blood T-cells may be correlated with the development of aGvHD after allo-HCT. Other surface markers like CD25, CD69, and CC-chemokine receptors were not found to be predictive markers in this study. Based on preclinical data from mouse models, a panel of surface markers combining alpha 4 beta 7 integrin with CD62L, CD162E, and CD162P is proposed to identify patients at risk for early aGvHD after allo-HCT.

Summary: This study investigates the role of IL-22 in female mice with acetaminophen-induced liver injury, demonstrating that testosterone and dihydrotestosterone can reduce IL-22 production in female splenocytes. The findings suggest a potential explanation for the increased IL-22 in female mice and splenocytes during inflammatory activation, and highlight the immunosuppressive effects of androgens in males.

Summary: IL-9, primarily produced by helper T cells, plays a critical role in COVID-19 by promoting viral spread and airway inflammation. This study demonstrates that blocking IL-9 can reduce airway inflammation, suggesting IL-9 as a potential therapeutic target for mitigating disease severity in COVID-19.

Summary: Cancer immunotherapy is more effective against hematological malignancies than solid tumors due to metabolic challenges in the tumor microenvironment. Mitochondria play a key role in CD8(+) T cell activation and effector function. Enhanced mitochondrial function is associated with improved T cell migration and effector function, highlighting the importance of mitochondrial metabolism in T cell responses.
