As a transmembrane protein, CD300e is primarily expressed in myeloid cells. It belongs to the CD300 glycoprotein family, functioning as an immune-activating receptor. Dysfunction of CD300e has been suggested in many diseases, such as infections, immune disorders, obesity, and diabetes, signifying its potential as a key biomarker for disease diagnosis and treatment. This review is aimed to explore the roles and potential mechanisms of CD300e in regulating oxidative stress, immune cell activation, tissue damage and repair, and lipid metabolism, shedding light on its role as a diagnostic marker or a therapeutic target, particularly for infections and autoimmune disorders.

TIGIT immune checkpoint (IC) has attracted great interest in recent years. It belongs to the PVR-like protein family, and it inhibits T and NK cell cytotoxic activities. TIGIT mediates its inhibitory effect by direct signaling through the cytoplasmic tail, CD155-mediated inhibition, or competition with the immune-activating receptor CD226.

Background: Near-infrared photoimmunotherapy (NIR-PIT) is a targeted cancer treatment that uses antibody-IR700 conjugates and selectively destroys cancer cells expressing a target antigen when exposed to near-infrared (NIR) light. NIR-PIT not only destroys targeted cancer cells but also induces anticancer immune activation. Currently, epidermal growth factor receptor (EGFR) is the only clinically approved target for NIR-PIT.

Beauvericin (BEA), a cyclic depsipeptide, is a mycotoxin of the enniatin family and the secondary metabolite of various toxigenic fungi. Multiple biological functions of BEA have been well investigated, such as anti-cancer, anti-inflammatory, anti-microbial, and immune-activating functions. In a recent study, we showed that BEA can target Toll-like receptor 4 (TLR4) to induce dendritic cell (DC) activation.

Background: Kidney Renal Clear Cell Carcinoma (KIRC) is a prevalent urinary malignancies worldwide. Glycosylation is a key post-translational modification that is essential in cancer progression. However, its relationship with prognosis, tumour microenvironment (TME), and treatment response in KIRC remains unclear.

While interferon-alpha (IFN-α) demonstrates potent antineoplastic activity against hepatocellular carcinoma (HCC), but many patients have a low response rate and may even develop resistance to it. It is necessary to find new strategies to reduce IFN-α resistance and improve its efficacy. RAR-related orphan receptor gamma t (RORγt) agonists exhibit dual immunomodulatory functions, demonstrating both immunosuppression-reducing and immune-activating properties.
