Summary: As the fifth pillar of cancer treatment, immunotherapy has revolutionized therapeutic strategies by focusing on the host's immune system. The discovery of immune-modulatory effects for kinase inhibitors has opened up new possibilities in this approach, as these small molecule inhibitors not only directly target essential proteins for tumor survival and proliferation, but also stimulate immune responses against malignant cells.

Summary: Small-cell lung cancer (SCLC) is an aggressive disease with limited treatment options and poor survival rates. While there have been significant advancements in the treatment of non-small cell lung cancer (NSCLC), SCLC has not seen the same level of progress. This is due, in part, to the complex and heterogeneous nature of SCLC tumors. This review explores the current treatment paradigm of SCLC, recent advances in immunotherapy, challenges in identifying predictive biomarkers, and potential future directions in SCLC treatment research.

Summary: NK cells play a crucial role in the innate immune system and can enhance adaptive immune responses. The activation of NK cells is regulated by a balance of inhibitory and activating receptors. These cells are potent producers of proinflammatory cytokines and can elicit strong antitumor responses through secretion of perforin and granzyme B. Strategies to enhance NK cell responses are being evaluated in clinical trials to improve immunotherapy effectiveness.

Summary: Immunotherapy has revolutionized cancer treatment, with current therapies mostly based on antibodies. However, these therapies have limitations in terms of pharmacokinetics and immunogenicity. To overcome these limitations, researchers have focused on developing small molecule-based immunotherapy. This review provides an overview of the progress in small molecule-based immunomodulators for cancer therapy, including targeting PD-1/PD-L1, chemokine receptors, STING, TLR, etc. The importance of combining small molecule-based immunomodulators with therapeutic antibodies is also highlighted.

Summary: In our initial publication, we demonstrated that small molecules can inhibit phagocytosis based on in vitro testing of over 200 compounds. We found four hit molecules with pyrazole core structure in a chemical library screening. Further evaluation resulted in the selection of two lead compounds with negligible toxicity and high efficacy in inhibiting phagocytosis. The rational development of these discoveries will lead to the selection of a lead compound(s) for pre-clinical evaluation through independent synthesis and in vivo activities.

Summary: Cellular mitophagy refers to the process in which cells selectively wrap and degrade damaged mitochondria through autophagy, thus maintaining mitochondrial and intracellular homeostasis. In recent years, mitophagy has gained attention as a research hotspot in the pathogenesis of various clinical diseases. It has been discovered that regulating mitophagy may open up new directions for disease treatment. Additionally, there have been reports of small molecule modulators of mitophagy, providing opportunities to understand the process and potential for therapeutic development.

Summary: Developing optimal T-cell response assays for SARS-CoV-2 is crucial for measuring immunity duration and vaccine efficacy. By using immunoinformatics analysis, we identified 57 immunogenic peptides with potential global cellular immune response coverage. 18 of these peptides have limited homology to seasonal human coronaviruses, making them promising candidates for specific T-cell immunity tests for SARS-CoV-2. Two peptides elicited effector responses in CD8+ T cells from SARS-CoV-2 convalescent patients.

Summary: Studies have shown that overcoming resistance to in vivo T-cell therapy can be achieved through the sequential infusion of two different allogeneic T-cell therapies restricted by different HLA alleles targeting EBV. Furthermore, the combination of inhibition of the programmed cell death protein-1/programmed death-ligand 1 axis with EBV-specific T-cell therapy significantly improves overall survival in tumor-bearing mice.

Summary: Researchers have designed a novel bivalent subunit vaccine against CMV, which combines CMV-encoded oligomeric glycoprotein B, polyepitope protein, and a TLR9 agonist to induce both humoral and cellular immune responses. The vaccine generated durable anti-viral antibodies and CMV-specific T cell responses in mice, and showed the potential to prevent CMV-associated complications.

Summary: Epithelial cancers have high mortality rates, but immunotherapies, particularly immune checkpoint blockade, have emerged as powerful treatment options. However, these cancers are often resistant to immunotherapies, making it crucial to boost their effectiveness. Small molecule inhibitors can target cancer proteins and enhance immune cell performance. This review focuses on using small molecule inhibitors to enhance the efficacy of immune checkpoint blockade.

Summary: This study demonstrates that most recipients of the ChAdOx1-S vaccine generated a T helper 1 response (IFN-gamma and/or IL-2) following the first dose of the vaccine, with a strong correlation between the magnitude of the IFN-gamma and IL-2 response. While some individuals showed production of other cytokines without generating IFN-gamma and IL-2, there was no correlation in magnitude, nor was there a correlation between sex or age and the magnitude of the response.
