Our co-culture system revealed the non-cell autonomous adverse effects of GM-CSF MΦ in individuals with ASD on neurons, mediated by interleukin-1α and TNF-α. These results may support the immune dysfunction hypothesis of ASD, providing new insights into its pathology.

DelNS1-GM-CSF displayed potent oncolytic activity against HCC and stimulated intra-tumor T-cell infiltration through activation of the JAK2-STAT3 pathway. Combination therapy with delNS1-GM-CSF and PD-1 blockade represents a promising immunotherapeutic strategy for HCC.

The autocrine cytokines, including GM-CSF, LIF, and OSM, contribute to constitutive STAT3/5 activation in TF-1(R140Q) cells, thereby modulating IDH2/R140Q-mediated malignant proliferation in TF-1 cells. Targeting STAT3/5 phosphorylation may be a novel strategy for the treatment of AML in patients harboring the IDH2/R140Q mutation. Video Abstract.

As a result, TAM induced by EBV abortive lytic cycle promotes NPC angiogenesis, invasion, and migration. Overall, this study elucidated the role of the EBV lytic life cycle in the late development of NPC and revealed a mechanism underlying the ZTA-mediated establishment of the tumor microenvironment (TME) that promotes NPC late-stage progression.

RADD demonstrates the ability to determine a quantitative analysis of DNA damage and repair in ovarian cancer samples. Considering its rapid turnaround time and correlation with HR status, RADD has potential use in determining clinical trial candidates stratified by HR status. Additionally, RADD correlates with known predictive biomarker CD39 for response with immunotherapy.

Adoptively transferred ThGM cells suppressed CRC growth whereas mTORC1 inhibition abolished this effect. mTORC1 is essential for the anti-CRC activity of ThGM cells.

In summary, ThGM cells in the PF and ELs might exacerbate endometriotic inflammation. IL-35 might suppress the function of ThGM cells via IL-35R.

Ovine IFN-τ may be an effective immunotherapeutic cytokine for the treatment of TNBC.

The use of UCB CD34+ HSCs to generate ILC1s, especially after being engineered with a CAR, could allow for a readily available supply of ILC1s to be produced for human adoptive transfer studies. Our findings provide evidence that targeting human ILC1s may be a promising therapeutic approach for extending disease-free survival in patients with AML.

To summarize, we show that normal myeloid cells have beneficial effects on CAR T cell function, and targeting these same myeloid cells is detrimental to CAR T cell activity. These findings provide insight into the reason for suboptimal CAR T cell activity in AML, and show that independent of target antigen and CAR construct, the nature of the cells being targeted can change the effectiveness of this therapy.

Targeting this axis diminished the neurotoxicity associated with this therapy. This study provides a rationale for testing TAK1-inhibition in a clinical trial for treating CD19 CAR-T cell-induced neurotoxicity.

A total of 91 pts are included in this analysis (initial melanoma cohort, 16 pts; R-D cohort, 75 pts; data cut: Dec 30, 2022). The overall objective response rate (ORR) was 37.4% (initial cohort, 37.5%; R-D cohort, 37.3%), and 18.7% of pts achieved complete response (CR; Table). The response rates seen were also encouraging when evaluated by prior anti–PD-1 therapy setting and disease stage (Table).

By contrast, DH82 cells lacked increased proliferation and motility. The significantly increased secretion of GM-CSF by persistently CDV-Ond-infected DH82 cells, the pH stability of this protein, and the lack of detrimental effects on DH82 cells renders this virus strain an interesting candidate for future studies aiming to enhance the oncolytic properties of CDV for the treatment of canine histiocytic sarcomas.

We sought to harness gene-modified tumor cells as a vaccine platform and developed cancer vaccines composed of breast cancer cells expressing GM-CSF (SV-BR-1-GM). Different types of cancer vaccines have been developed with moderate success, often hampered by lack of strong immunogenicity and complex manufacturing. BriaCell’s Bria OTS provides a solution by increasing vaccine immunogenicity and decreasing manufacturing costs while personalizing the therapy based on matching the patient’s HLA type.1.Lacher MD et al, Front Immunol. 2018 May 15;9:776

The combination was generally well tolerated, consistent with prior data. Enrollment into a registration-directed cohort of pts with anti-PD-1 failed cutaneous mel (n=125) and a cohort with anti-PD-1 failed NMSC (n=30) is ongoing.

These results show that high IL4/GMCSF levels are negatively associated with survival in EC. These relationships are independent of pathologic stage and are identified across modalities, histologic subtypes, and the presence/absence of neoadjuvant therapy.

A multi-factorial amplification protocol can effectively improve CXCR3 expression on the surface of activated CAR-T cells in vitro, as well as enhance the chemotaxis ability of CAR-T cells in vivo, which significantly inhibit the growth of liver cancer.

Mechanistically, it is revealed that Setd2-H3K36me3 loss leads to ectopic gain of H3K27me3 to downregulate Cxadr expression, which boosts the PI3K-AKT pathway and excessive expression of CXCL1 and GM-CSF, thereby promoting neutrophil recruitment and reprogramming toward an immunosuppressive phenotype. The study provides mechanistic insights into how tumor cell-intrinsic Setd2 deficiency strengthens the immune escape during pancreatic tumorigenesis, which may offer potential therapeutic implications for pancreatic cancer patients with SETD2 deficiency.
