Anti-PD-L1 chimeric antigen receptor natural killer cell: Characterization and functional analysis.

Like their natural counterparts, chimeric antigen receptor-engineered cells are prone to suppression by inhibitory signals, such as PD-L1, expressed by tumors or suppressor cells in the tumor microenvironment. Consequently, they become impaired, resulting in immune cell exhaustion, tumor progression, and resistance to other therapies. In this study, we developed an anti-PD-L1-CAR NK cell with efficient activity and a notable PD-L1-specific response toward tumor cell lines.

Mononuclear cells were isolated from 50 tumor-draining lymph nodes of untreated patients with BC and stained with antibodies against the markers CD8, CD95, CD45RO and CCR7.

Advancements in Melanoma Therapies: From Surgery to Immunotherapy.

Melanoma is defined as the most aggressive and deadly form of skin cancer. The treatment of melanoma depends on the disease stage, tumor location, and extent of its spread from its point of origin. Melanoma treatment has made significant advances, notably in the context of targeted and immunotherapies.

The genomic landscape of the immune system in lung cancer: present insights and continuing investigations.

Lung cancer is one of the most prevalent malignancies worldwide, contributing to over a million cancer-related deaths annually.

miR-939, as an important regulator in various cancers pathogenesis, has diagnostic, prognostic, and therapeutic values: a review.

Background: MicroRNAs (miRNAs or miRs) are highly conserved non-coding RNAs with a short length (18-24 nucleotides) that directly bind to a complementary sequence within 3'-untranslated regions of their target mRNAs and regulate gene expression, post-transcriptionally. They play crucial roles in diverse biological processes, including cell proliferation, apoptosis, and differentiation. In the context of cancer, miRNAs are key regulators of growth, angiogenesis, metastasis, and drug resistance.
