Here we explore the current clinical landscape of CAR NK cells, and their application in hematologic malignancies and solid cancers, as well as their potential for treating autoimmune disorders. Our analysis draws from data collected from 120 clinical trials focused on CAR NK cells, and presents insights into the demographics and characteristics of these studies. We further outline the specific targets and diseases under investigation, along with the major cell sources, genetic modifications, combination strategies, preconditioning- and dosing regimens, and manufacturing strategies being utilized. Initial results from 16 of these clinical trials demonstrate promising efficacy of CAR NK cells, particularly in B cell malignancies, where response rates are comparable to those seen with CAR T cells but with lower rates of severe adverse effects, such as cytokine release syndrome (CRS), immune effector cell-associated neurotoxicity syndrome (ICANS), and graft-versus-host disease (GvHD). However, challenges remain in solid tumor applications, where only modest efficacy has been observed to date. Our analysis reveals that research is increasingly focused on enhancing CAR NK cell persistence, broadening their therapeutic targets, and refining manufacturing processes to improve accessibility and scalability. With recent advancements in NK cell engineering and their increased clinical applications, CAR NK cells are predicted to become an integral component of next-generation immunotherapies, not only for cancer but potentially for immune-mediated diseases as well.</p>","PeriodicalId":12180,"journal":{"name":"Experimental Hematology & Oncology","volume":"14 1","pages":"46"},"PeriodicalIF":9.4,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11951618/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143729376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The envelope protein of the HBV virus, known as hepatitis B surface antigen (HBsAg), is a key indicator of increased risk for developing HCC in HBsAg-positive individuals. The HBsAg seroclearance status is found to be associated with recurrence in HCC patients undergoing hepatectomy.

Although MMP14 plays an important role in inflammation and cancer, the regulation and role of MSC-derived MMP14 in acute myeloid leukemia (AML) are largely unknown. Here, we found that AML patient-derived MSCs (AML-MSCs) were more supportive of AML cell growth compared to healthy donor-derived MSCs (HD-MSCs). Moreover, AML-MSCs and HD-MSCs showed significant differences in gene expression and protein expression profiles. Knockdown of MMP14 in MSCs inhibited the CFU-F ability of MSC cells and increased the proportion of cells in the G0 phase, thereby inhibiting proliferation. Co-culture with MSCs inhibited the proliferation and cell cycle progression of leukemia cells, while increasing the apoptosis rate, thus impairing the leukemogenic potential of AML cells both in vitro and in vivo. Mechanistic studies revealed that MMP14-mediated alterations in the AML stromal microenvironment are driven by PGE2 secretion and activation of the JAK-STAT pathway, promoting leukemia progression. Notably, inhibition of MMP14 can attenuate the chemotherapy resistance of AML cells induced by MSCs to cytarabine (Ara-C).
