Background: Accumulating evidence suggests that the presynaptic protein α-synuclein (α-syn), is involved in the pathophysiology of AD and elevated in the cerebrospinal fluid (CSF). The role of Natural Killer (NK) cells of the innate immune system in AD has largely been overlooked. In a murine model, depletion of NK cells augmented the accumulation of pathological α-syn.

Killer Cell Lectin Like Receptor D1 (KLRD1) plays a crucial role in antitumor immunity. However, its expression patterns across various cancers, its relationship with patient prognosis, and its potential as an immunotherapy target remain inadequately understood. We analyzed KLRD1 expression across various cancer types using multi-omics data from The Cancer Genome Atlas (TCGA), Genotype-Tissue Expression (GTEx), and Gene Expression Omnibus (GEO) databases, correlating it with patient prognosis.

The role of γδ T cells in antitumor responses has gained significant attention due to their unique major histocompatibility complex (MHC)-independent killing mechanisms, which distinguish them from conventional αβ T cells. Notably, γδ tumor-infiltrating lymphocytes (TILs) have been identified as favorable prognostic markers in various cancers. However, γδ TIL subsets, including Vδ1, Vδ2, and Vδ3, exhibit distinct prognostic implications and phenotypes from one another within the tumor microenvironment (TME).

This case study explores the effectiveness of autologous cytokine-induced killer (CIK) cell-based immunotherapy in a 49-year-old male patient with inoperable stage IIIb cholangiocarcinoma, characterized by high levels of the sodium-dependent vitamin C transporter-2 (SVCT2) in immune cells. Despite an initial lack of tumor reduction following chemotherapy, the patient showed a significant decrease in tumor markers and stabilization of the tumor after undergoing radiation and proton therapy. Subsequently, CIK cell therapy, combined with high-dose vitamin C, was administered 52 times over 6 years.

Interferon gamma (IFNγ) is well-known for its ability to stimulate immune cells in response to pathogen infections and cancer. To develop an effective cancer therapeutic vaccine, CT26 colon carcinoma cells were genetically modified to express IFNγ either as a secreted form (sIFNγ) or as a membrane-bound form. For the membrane-bound expression, IFNγ was fused with Fas (mbIFNγ/Fas), incorporating the extracellular cysteine-rich domains, transmembrane, and cytoplasmic domains of Fas.
