B Cells Are Required to Generate Optimal Anti-Melanoma Immunity in Response to Checkpoint Blockade. Front Immunol 2022; 13:794684. [PMID: 35720386 PMCID: PMC9204262 DOI: 10.3389/fimmu.2022.794684] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Accepted: 04/20/2022] [Indexed: 12/24/2022] Open
Abstract
Immunotherapies such as checkpoint blockade therapies are known to enhance anti-melanoma CD8+ T cell immunity, but only a fraction of patients treated with these therapies achieve durable immune response and disease control. It may be that CD8+ T cells need help from other immune cells to generate effective and long-lasting anti-tumor immunity or that CD8+ T cells alone are insufficient for complete tumor regression and cure. Melanoma contains significant numbers of B cells; however, the role of B cells in anti-melanoma immunity is controversial. In this study, B16 melanoma mouse models were used to determine the role of B cells in anti-melanoma immunity. C57BL/6 mice, B cell knockout (KO) C57BL/6 mice, anti-CD19, and anti-CXCL13 antibody-treated C57BL/6 mice were used to determine treatment efficacy and generation of tumor-specific CD8+ T cells in response to PD-L1 blockade alone or combination with TLR-7/8 activation. Whole transcriptome analysis was performed on the tumors from B cell depleted and WT mice, untreated or treated with anti-PD-L1. Both CD40-positive and CD40-negative B cells were isolated from tumors of TLR-7/8 agonist-treated wild-type mice and adoptively transferred into tumor-bearing B cell KO mice, which were treated with anti-PD-L1 and TLR-7/8 agonist. Therapeutic efficacy was determined in the presence of activated or inactivated B cells. Microarray analysis was performed on TLR-7/8-treated tumors to look for the B cell signatures. We found B cells were required to enhance the therapeutic efficacy of monotherapy with anti-PD-L1 antibody and combination therapy with anti-PD-L1 antibody plus TLR-7/8 agonist. However, B cells were not essential for anti-CTLA-4 antibody activity. Interestingly, CD40-positive but not CD40-negative B cells contributed to anti-melanoma immunity. In addition, melanoma patients' TCGA data showed that the presence of B cell chemokine CXCL13 and B cells together with CD8+ T cells in tumors were strongly associated with improved overall survival. Our transcriptome data suggest that the absence of B cells enhances immune checkpoints expression in the tumors microenvironment. These results revealed the importance of B cells in the generation of effective anti-melanoma immunity in response to PD-1-PD-L1 blockade immunotherapy. Our findings may facilitate the design of more effective anti-melanoma immunotherapy.

IL-1α Mediates Innate and Acquired Resistance to Immunotherapy in Melanoma. JOURNAL OF IMMUNOLOGY (BALTIMORE, MD. : 1950) 2021; 206:1966-1975.

Abstract
Inflammation has long been associated with cancer initiation and progression; however, how inflammation causes immune suppression in the tumor microenvironment and resistance to immunotherapy is not well understood. In this study, we show that both innate proinflammatory cytokine IL-1α and immunotherapy-induced IL-1α make melanoma resistant to immunotherapy. In a mouse melanoma model, we found that tumor size was inversely correlated with response to immunotherapy. Large tumors had higher levels of IL-1α, Th2 cytokines, polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs), and regulatory T cells but lower levels of IL-12, Th1 cytokines, and activated T cells. We found that therapy with adenovirus-encoded CD40L (rAd.CD40L) increased tumor levels of IL-1α and PMN-MDSCs. Blocking the IL-1 signaling pathway significantly decreased rAd.CD40L-induced PMN-MDSCs and their associated PD-L1 expression in the tumor microenvironment and enhanced tumor-specific immunity. Similarly, blocking the IL-1 signaling pathway improved the antimelanoma activity of anti-PD-L1 Ab therapy. Our study suggests that blocking the IL-1α signaling pathway may increase the efficacy of immunotherapies against melanoma.

Abstract
BACKGROUND Cytomorphological assessment of erosive skin tumours offers a rapid and minimally invasive way to obtain a diagnosis. However, the studies so far conducted on this method have been relatively small. AIM To conduct a large retrospective study on cytomorphological assessment of erosive skin tumours. METHODS In this study, 86 cytological smears prepared from erosive cutaneous tumours clinically suspicious for melanoma were examined to test the diagnostic accuracy and practicability of cytomorphological evaluation of such tumours, and to compare the assessments of two investigators with different experience levels. In a subgroup of tumours, cytological assessment was compared with dermoscopic evaluation. RESULTS There was agreement in the cytological and histopathological results for 68 of 86 cases (79%) assessed by the experienced investigator and in 64 of 86 cases (74%) assessed by the inexperienced investigator. The diagnosis was confirmed cytologically in 39 and 34 of 42 melanomas, and in 28 and 27 of 35 basal cell carcinomas, respectively. The sensitivity of the cytodiagnosis was not significantly different between the two investigators. The dermoscopic evaluation showed good agreement with the cytological results for melanoma (82.4%), although use of dermoscopy was only possible for 49.9% of the lesions because of difficulties with the samples. CONCLUSIONS Cytological assessment of erosive melanoma and BCC lesions is a useful tool for gaining additional information on clinically uncertain skin tumours, and shows good agreement between different investigators.
