9-kDa Granulysin is a protein present in the granules of human activated cytotoxic T lymphocytes and natural killer cells. It has been shown to exert cytolytic activity against a wide variety of microbes: bacteria, fungi, yeast and protozoa. Recombinant isolated granulysin is also capable of inducing tumor cell death, so it could be used as an anti-tumor therapy.

In this study, we revealed a critical role of eukaryotic elongation factor-2 kinase (eEF-2K), a negative regulator of protein synthesis, in regulating T cells during vaccinia virus (VACV) infection. We found that eEF-2K-deficient (eEF-2K⁻/⁻) mice exhibited a significantly higher proportion of VACV-specific effector CD8 T cells without compromising the development of VACV-specific memory CD8 T cells. RNA sequencing demonstrated that eEF-2K⁻/⁻ VACV-specific effector CD8 T cells had enhanced functionality, which improves their capacity to combat viral infection during the effector phase.

The development of mesothelin (MSLN) epitope reactive T cells is observed in mice that are immunized with the MSLN vaccine. Engineered T cells expressing MSLN-reactive high-affinity TCR exhibit extraordinary therapeutic effects for invasive pancreatic ductal adenocarcinoma in a mouse model. However, the generation of MSLN-reactive T cells through the introduction of MSLN-deficient thymus and the transplantation of the latter as a cure for cancer treatment have not been tested to date.

Neutropenia in rheumatoid arthritis (RA) is a problem that often needs to be addressed. Side effects of basic antirheumatic treatment, infections or substrate deficiencies are common causes; however, T‑cell large granular lymphocytic (T-LGL) leukemia, a mature T‑cell neoplasm, can also lead to autoimmune cytopenia. The T‑LGL leukemia can be associated not only with RA but also with other autoimmune diseases or neoplasms.

CD73 is ubiquitously expressed and regulates critical functions across multiple organ systems. The sequential actions of CD39 and CD73 accomplish the conversion of adenosine triphosphate to adenosine and shift the adenosine triphosphate-driven proinflammatory immune cell milieu toward an anti-inflammatory state. This immunological switch is a major mechanism by which regulatory T (Treg) cells control inflammation.
