简介

Involved in alveolar fluid homeostasis via regulation of alveolar epithelial tight junction composition and therefore ion transport and solute permeability, potentially via downstream regulation of the actin cytoskeleton organization and beta-2-adrenergic signaling (By similarity). Required for lung alveolarization and maintenance of the paracellular alveolar epithelial barrier (By similarity). Acts to maintain epithelial progenitor cell proliferation and organ size, via regulation of YAP1 localization away from the nucleus and thereby restriction of YAP1 target gene transcription (By similarity). Acts as a negative regulator of RANKL-induced osteoclast differentiation, potentially via relocation of TJP2/ZO-2 away from the nucleus, subsequently involved in bone resorption in response to calcium deficiency (By similarity). Mediates the osteoprotective effects of estrogen, potentially via acting downstream of estrogen signaling independently of RANKL signaling pathways (By similarity). Involved in the maintenance of homeostasis of the alveolar microenvironment via regulation of pH and subsequent T-cell activation in the alveolar space, is therefore indirectly involved in limiting C. neoformans infection. Required for the formation of the gastric paracellular barrier via its role in tight junction formation, thereby involved in the response to gastric acidification.

Gut microbiota modulate CD8 ⁺ T cell immunity in gastric cancer through Butyrate/GPR109A/HOPX

Article

作者: Ou, Jinzhou ; Li, Guoxin ; Xie, Lang ; Yu, Xiang ; Shen, Guodong ; Zhao, Cuiyin ; Ren, Yingxin ; Liang, Junxian ; Chen, Zhian ; Zou, Zhaowei ; Li, Zhenyuan ; Hu, Yanfeng ; Wang, Lingzhi

The gut microbiota and Short-chain fatty acids (SCFAs) can influence the progression of diseases, yet the role of these factors on gastric cancer (GC) remains uncertain. In this work, the analysis of the gut microbiota composition and SCFA content in the blood and feces of both healthy individuals and GC patients indicated that significant reductions in the abundance of intestinal bacteria involved in SCFA production were observed in GC patients compared with the controls. ABX mice transplanted with fecal microbiota from GC patients developed more tumors during the induction of GC and had lower levels of butyric acid. Supplementation of butyrate during the induction of gastric cancer along with H. pylori and N-methyl-N-nitrosourea (MNU) in WT in GPR109A^-/-mice resulted in fewer tumors and more IFN-γ⁺ CD8⁺ T cells, but this effect was significantly weakened after knockout of GPR109A. Furthermore, In vitro GC cells and co-cultured CD8⁺ T cells or CAR-Claudin 18.2⁺ CD8⁺ T cells, as well as in vivo tumor-bearing studies, have indicated that butyrate enhanced the killing function of CD8⁺ T cells or CAR-Claudin 18.2⁺ CD8⁺ T cells against GC cells through G protein-coupled receptor 109A (GPR109A) and homologous domain protein homologous box (HOPX). Together, these data highlighted that the restoration of gut microbial butyrate enhanced CD8⁺ T cell cytotoxicity via GPR109A/HOPX, thus inhibiting GC carcinogenesis, which suggests a novel theoretical foundation for GC management against GC.

Immune checkpoint inhibitors in advanced gastroesophageal adenocarcinoma: a series of patient-level meta-analyses in different programmed death-ligand 1 subgroups

Article

作者: Fong, K Y ; Zhao, J.J. ; Pietrantonio, F. ; Mai, A S ; Seong, J.T.C. ; Sundar, R ; Sundar, R. ; Kato, K. ; Moehler, M ; Zhao, J J ; Yap, D.W.T. ; Mai, A.S. ; Moehler, M. ; Leone, A G ; Smyth, E. ; Pietrantonio, F ; Yap, D W T ; Leone, A.G. ; Kato, K ; Fong, K.Y. ; Seong, J T C ; Smyth, E

BACKGROUNDWhile the benefit of immune checkpoint inhibitors (ICI) is well established in programmed death-ligand 1 high (PD-L1_high) advanced gastroesophageal adenocarcinoma (GEAC), there remains significant controversy about their benefit in PD-L1_low GEAC. To elucidate the benefit of ICI in PD-L1_low and PD-L1_negative GEAC, we conducted an analysis leveraging individual patient data (IPD) extracted from Kaplan-Meier (KM) plots of pivotal trials.METHODSKM curves from randomized clinical trials investigating the efficacy of ICI for advanced GEAC were extracted from published articles. IPD were extracted from the reported curves, and, in the case of unreported KM plots, KMSubtraction was used to retrieve survival data. A patient-level meta-analysis was conducted for PD-L1_low tumors.RESULTSIn the human epidermal growth factor receptor 2 (HER2)-negative setting, pooled PD-L1 combined positive score (CPS) 1-4 subgroup KM plots from KEYNOTE-859, CHECKMATE-649, and RATIONALE-305 showed a modest overall survival (OS) benefit with the addition of an anti-programmed cell death protein 1 (anti-PD-1) agent [hazard ratio (HR) 0.868, P = 0.018]. Similarly, a modest OS benefit was shown by our IPD meta-analysis of PD-L1 CPS 1-9 subgroups from KEYNOTE-859, KEYNOTE-062, and RATIONALE-305 (HR 0.840, P = 0.002.) Conversely, when CPS 5-9 subgroup KM plots from KEYNOTE-859 and RATIONALE-305 were pooled together, no significant OS benefit was found in the ICI-chemotherapy arm (HR 0.867, P = 0.181), although this subgroup was relatively small.CONCLUSIONSIn PD-L1_low HER-2 negative GEAC, the benefit of first-line ICI is modest, yet significant. Further translational work is warranted to better select patients who could benefit from immunotherapy in this setting. Meanwhile, alternative therapeutic options such as zolbetuximab in Claudin18.2-positive disease must be taken into account.

Claudin-18.2 Immunohistochemical Evaluation in Gastric and Gastroesophageal Junction Adenocarcinomas to Direct Targeted Therapy: A Practical Approach

Review

作者: Röcken, Christoph ; Rüschoff, Josef ; Kuwata, Takeshi ; Matkowskyj, Kristina A ; Fassan, Matteo

Claudin-18.2 (CLDN18.2) expression evaluated by immunohistochemistry is a new biomarker for gastric and gastroesophageal junction adenocarcinomas that will soon have market authorization for implementation into routine clinical practice. Despite successful testing in the setting of clinical trials, no specific practical testing guidelines have been proposed. Several pre-analytical and analytical variables may interfere with adequate CLDN18.2 staining interpretation, thus this article provides practical guidance on CLDN18.2 testing and scoring in gastric/gastroesophageal junction adenocarcinomas in order to identify patients who may respond to targeted therapy with monoclonal antibodies directed against CLDN18.2. Based on available data, moderate to strong (2+/3+) membrane staining in ≥75% of adenocarcinoma cells is the proposed cut-off for clinical use of the monoclonal antibody anti-CLDN18.2 (zolbetuximab).
