A recombinant co-stimulatory molecule capable of inducing multiple effects on varied immune cells when present in its soluble active form is termed as SA-4-1BBL. It has been reported to influence innate, adaptive, and regulatory immune cells. Recent studies confirmed its engagement with receptor, 4-1BB leading to collection of interleukin-2 (IL-2) that in turn overcomes Treg suppression. Further, a vast number of pre-clinical studies reported its therapeutic efficacy in the form of adjuvant subunit in cancer vaccines. Furthermore, it is also observed that it contributes significantly towards communication bridge of CD4 and NK cells. On the other hand, depletion of either NK or CD4 cells negated SA-4-1BBL's antitumor protection. The present review article is focused on the current updates of this molecule pertaining to the filed of cancer therapeutics or cancer preventives.

Allogeneic DNT cell therapy synergizes with T cells to promote anti-leukemic activities while suppressing GvHD.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a second-line treatment with curative potential for leukemia patients. However, the prognosis of allo-HSCT patients with disease relapse or graft-versus-host disease (GvHD) is poor. CD4 or CD8 conventional T (Tconv) cells are critically involved in mediating anti-leukemic immune responses to prevent relapse and detrimental GvHD.

Background: Immune cells within tumor tissues play important roles in remodeling the tumor microenvironment, thus affecting tumor progression and the therapeutic response. The current study was designed to identify key markers of plasma cells and explore their role in high-grade serous ovarian cancer (HGSOC).
Methods: We utilized single-cell sequencing data from the Gene Expression Omnibus (GEO) database to identify key immune cell types within HGSOC tissues and to extract related markers via the Seurat package.
The role of BATF in immune cell differentiation and autoimmune diseases.

As a member of the Activator Protein-1 (AP-1) transcription factor family, the Basic Leucine Zipper Transcription Factor (BATF) mediates multiple biological functions of immune cells through its involvement in protein interactions and binding to DNA. Recent studies have demonstrated that BATF not only plays pivotal roles in innate and adaptive immune responses but also acts as a crucial factor in the differentiation and function of various immune cells. Lines of evidence indicate that BATF is associated with the onset and progression of allergic diseases, graft-versus-host disease, tumors, and autoimmune diseases.

Background: Bacterial toxins are emerging as promising hallmarks of colorectal cancer (CRC) pathogenesis. In particular, Cytotoxic Necrotizing Factor 1 (CNF1) from E. coli deserves special consideration due to the significantly higher prevalence of this toxin gene in CRC patients with respect to healthy subjects, and to the numerous tumor-promoting effects that have been ascribed to the toxin in vitro.

Background And Aim: Hepatocellular carcinoma (HCC) is a highly immunogenic tumor and the third leading cause of cancer-related deaths worldwide with an increasing incidence. Therefore, the combination of immunotherapy with other approaches, such as anti-angiogenic agents and local area therapy, has become a new strategy for HCC treatment.
Methods: We searched PubMed and Web of Science and extracted publications relating to the radiofrequency ablation (RFA) and immunotherapy.
