Use of chimeric antigen receptors (CARs), as an immune cell therapy, has generated excellent clinical outcomes against hematologic tumors in recent years. Among them, the CAR-NK (natural killer) therapy has shown better efficacy, and less toxicity, than chimeric antigen receptor T-cell (CAR-T) therapy. In our phase II clinical trials, administering chimeric costimulatory converting receptor (CCCR)-NK92 cells on advanced non-small cell lung cancer patients proved efficacious in cell and animal experiments. However, we observed occurrence of cytokine release syndrome (CRS), a rare and unexpected side effect, never reported before during CAR-NK therapy. Here, we provide a detailed report of the patient’s case, emphasize on the need to pay attention to CRS in NK cell therapy, and suggest improvements that will minimize potential toxicity.

Therapeutic tumor neoantigen vaccines have been widely studied given their good safety profile and ability to avoid central thymic tolerance. However, targeting antigen‐presenting cells (APCs) and inducing robust neoantigen‐specific cellular immunity remain challenges. Here, a safe and broad‐spectrum neoantigen vaccine delivery system is proposed (GP‐Neoantigen) based on β‐1,3‐glucan particles (GPs) derived from Saccharomyces cerevisiae and coupling peptide antigens with GPs through convenient click chemistry. The prepared system has a highly uniform particle size and high APC targeting specificity. In mice, the vaccine system induced a robust specific CD8⁺ T cell immune response and humoral immune response against various conjugated peptide antigens and showed strong tumor growth inhibitory activity in EG7·OVA lymphoma, B16F10 melanoma, 4T1 breast cancer, and CT26 colon cancer models. The combination of the toll‐like receptors (TLRs) agonist PolyI:C and CpG 2395 further enhanced the antitumor response of the particle system, achieving complete tumor clearance in multiple mouse models and inducing long‐term rejection of reinoculated tumors. These results provide the broad possibility for its further clinical promotion and personalized vaccine treatment.

Endometrial injury is the main fact leading to infertility. Current treatments of endometrial injury present many problems, such as unable to achieve desired effects due to low retention and the inherent potential risk of injury. Besides, it is important to the development of bioinspired material that can mimic the natural tissue and possess native tissue topography. Hydrogel is a kind of bioinspired superhydrophilic materials with unique characteristics, such as excellent biocompatibility, biodegradability, porosity, swelling, and cross-linkage. These unique physiochemical properties of bioinspired hydrogels enable their promising application as novel delivery platform and alternative therapies for endometrial injury. In this mini review, we summarize the recent advances in bioinispred hydrogel-based delivery system for endometrial repair, including as a post-operative physical barrier and therapeutic delivery system. In addition, present status, limitations, and future perspectives are also discussed.

According to the World Health Organization’s statistics, cancer is the second leading cause of death worldwide, following cardiovascular diseases. Despite significant progress in the field of cancer treatment in recent years, cancer remains one of the main factors shortening human life expectancy. The field of cancer research is increasingly focusing on the role of tumor-related oncogenes and heterogeneous proteins in the development of cancer. Studies indicate that there is a close connection between solid tumors and epithelial splicing regulatory protein 1 (ESRP1). ESRP1 is a key intracellular molecule that plays a crucial role in cell growth and differentiation. As an emerging biomarker, ESRP1 has a decisive impact on the formation and development of solid tumors by regulating the alternative splicing of CD44 and the epithelial-mesenchymal transition (EMT) process. Research shows that abnormal expression of ESRP1 is closely related to the formation and development of various solid tumors, including breast cancer, lung cancer, stomach cancer, and others, and is closely associated with the invasiveness, metastasis, and poor prognosis of tumors. Therefore, given ESRP1’s critical role in cancer development, it is gradually becoming a potential biomarker and therapeutic target. This review primarily discusses the molecular mechanisms of ESRP1 in regulating cancer metastasis, particularly its regulatory effects on CD44 splicing and the EMT process. These research findings provide new targets for cancer treatment, aiming to bring more precise diagnosis and more effective treatment strategies to patients.
