Background: CD3 + CD20 + T cells (T cells) are a subset of lymphocytes in the human body that are associated with inflammation. They originate from T cells interacting with B cells, and their levels are abnormally elevated in individuals with immune disorders, as well as in some cancer patients. The interplay between tumor immunity and inflammation is intricate, yet the specific involvement of T cells in local tumor immunity remains uncertain, with limited research on their subtypes.

The neuromuscular junction shows several degenerative changes with aging, resulting in a reduction of transmission efficacy. These changes, paired with low-grade chronic inflammation, were considered triggers of the aging muscle processes. The main objective of this study is to assess the role of leukocyte count-derived ratios, nerve conduction velocity (NCV), and compound muscle action potential (CMAP) in determining time-dependent reduction in lower limb muscle explosive strength, a condition that has been defined as powerpenia.

Background: Hypoxia in tumor cells is linked to increased drug resistance and more aggressive behavior. In pancreatic cancer, the tumor microenvironment is notably hypoxic and exhibits strong immunosuppressive properties. Given that immunotherapy is now approved for pancreatic cancer treatment, further understanding of how pancreatic tumor cell hypoxia influences T-cell cytotoxicityis essential.

Foxp3-expressing CD4 regulatory T (Treg) cells play a crucial role in suppressing autoimmunity, tolerating food antigens and commensal microbiota, and maintaining tissue integrity. These multifaceted functions are guided by environmental cues through interconnected signaling pathways. Traditionally, Treg fate and function were believed to be statically determined by the forkhead box protein Foxp3 that directly binds to DNA.

Background: Methicillin-resistant (MRSA) poses a significant challenge in clinical environments due to its resistance to standard antibiotics. Protein A (SpA), a crucial virulence factor of MRSA, undermines host immune responses, making it an attractive target for vaccine development. This study aimed to identify potential epitopes within SpA that could elicit robust immune responses, ultimately contributing to the combat against multidrug-resistant (MDR) MRSA.
