The Function of the Histamine H4 Receptor in Inflammatory and Inflammation-Associated Diseases of the Gut.

Int J Mol Sci 2021 Jun 6;22(11). Epub 2021 Jun 6.

Institute of Pharmacology, Hannover Medical School, D-30625 Hannover, Germany.

Histamine is a pleiotropic mediator involved in a broad spectrum of (patho)-physiological processes, one of which is the regulation of inflammation. Compounds acting on three out of the four known histamine receptors are approved for clinical use. These approved compounds comprise histamine H1-receptor (HR) antagonists, which are used to control allergic inflammation, antagonists at HR, which therapeutically decrease gastric acid release, and an antagonist at HR, which is indicated to treat narcolepsy.

Intratumoral CXCR5CD8T associates with favorable clinical outcomes and immunogenic contexture in gastric cancer.

Nat Commun 2021 05 25;12(1):3080. Epub 2021 May 25.

Department of Gastric Surgery, Shanghai Cancer Center, Fudan University, Shanghai, China.

Studies that examined an association between CD8T and prognosis in gastric cancer are inconsistent, and a distinct population of CXCR5CD8T associated with better overall survival has been reported among various malignancies. Here, we show that the abundance of intratumoral CXCR5CD8T cells is associated with better overall survival in patients with gastric cancer. Patients with TNM II + III gastric cancer with higher intratumoral CXCR5CD8T cell infiltration are more likely to benefit from adjuvant chemotherapy. Read More

Semin Thromb Hemost 2021 May 14. Epub 2021 May 14.

Department of Medical Oncology, Centro Hospitalar Universitário do Porto, Institute of Biomedical Sciences Abel Salazar, University of Porto, Porto, Portugal.

Cancer-related venous thromboembolism (VTE) remains a major health problem, accounting for at least 18% of all cases of VTE. Cancer patients with VTE have worse prognosis than those without VTE. Prophylaxis reduces VTE risk, but it is not feasible for all outpatients with cancer due to an increased bleeding risk. Read More

Glucocorticoids and Androgens Protect From Gastric Metaplasia by Suppressing Group 2 Innate Lymphoid Cell Activation.

Gastroenterology 2021 May 7. Epub 2021 May 7.

Molecular Endocrinology Group, Signal Transduction Laboratory, North Carolina. Electronic address:

Background & Aims: The immune compartment is critical for maintaining tissue homeostasis.

Tumor-Associated Macrophages and Inflammatory Microenvironment in Gastric Cancer: Novel Translational Implications.

Int J Mol Sci 2021 Apr 7;22(8). Epub 2021 Apr 7.

Department of Radiology, IRCCS Azienda Ospedaliero-Universitaria di Bologna, 40138 Bologna, Italy.

Gastric cancer (GC) represents the fifth most frequently diagnosed cancer worldwide, with a poor prognosis in patients with advanced disease despite many improvements in systemic treatments in the last decade. In fact, GC has shown resistance to several treatment options, and thus, notable efforts have been focused on the research and identification of novel therapeutic targets in this setting. The tumor microenvironment (TME) has emerged as a potential therapeutic target in several malignancies including GC, due to its pivotal role in cancer progression and drug resistance. Read More

J Int Med Res 2021 Apr;49(4):3000605211006602

Division of Gastroenterology & Hepatology, The University of Hong Kong-Shenzhen Hospital, Shenzhen, China.

To the best of our knowledge, there are no previous reports of a gastro-colic fistula (GCF) secondary to primary high-grade B-cell gastric lymphoma associated with acquired immunodeficiency syndrome (AIDS). Here, we report a 37-year-old man who presented with paroxysmal abdominal pain for 4 months, diarrhea for 15 days and weight loss of 4 kg. He had a history of human immunodeficiency virus (HIV) infection and was diagnosed with AIDS in 2013. Read More

A selective HDAC8 inhibitor potentiates antitumor immunity and efficacy of immune checkpoint blockade in hepatocellular carcinoma.

Sci Transl Med 2021 04;13(588)

School of Biomedical Sciences, The Chinese University of Hong Kong, Hong Kong SAR 999077, China.

Insufficient T cell infiltration into noninflamed tumors, such as hepatocellular carcinoma (HCC), restricts the effectiveness of immune-checkpoint blockade (ICB) for a subset of patients. Epigenetic therapy provides further opportunities to rewire cancer-associated transcriptional programs, but whether and how selective epigenetic inhibition counteracts the immune-excluded phenotype remain incompletely defined. Here, we showed that pharmacological inhibition of histone deacetylase 8 (HDAC8), a histone H3 lysine 27 (H3K27)-specific isozyme overexpressed in a variety of human cancers, thwarts HCC tumorigenicity in a T cell-dependent manner.

Pathological Complete Remission of Liver Metastases Correlates With Elimination of Tumor-infiltrating Tregs in Gastric Cancer.

Anticancer Res 2021 Mar;41(3):1571-1577

Department of Gastroenterological Surgery, Hyogo College of Medicine, Nishinomiya, Japan.

Background/aim: Tumor-infiltrating Foxp3 regulatory T-cells (Ti-Tregs) promote tumor progression and contribute to poor prognosis in gastric cancer, but the relationship between Ti-Tregs and response to chemotherapy for liver metastases from gastric cancer (LMGC) is unclear. We estimated the correlation between pathological response to chemotherapy and Ti-Tregs in LMGC.

Patients And Methods: Ti-Tregs were analyzed with immunohistochemistry as CD3 Foxp3 cells in patients with synchronous LMGC. Read More

Monitoring FTD in the peripheral blood mononuclear cells of elderly patients with metastatic colorectal cancer administered FTD plus bevacizumab as first-line treatment.

Cancer Sci 2021 Jun 3;112(6):2436-2441. Epub 2021 May 3.

Department of Surgery and Sciences, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan.

Trifluridine/tipiracil (FTD/TPI) is an orally administrated anticancer drug with efficacy validated for patients with metastatic colorectal cancer (mCRC) or gastric cancer. FTD, a key component of FTD/TPI, exerts antitumor effects via its incorporation into DNA. Using specific antibodies against bromodeoxyuridine, FTD incorporation into DNA is detected in tumors and peripheral blood mononuclear cells (PBMC) of patients with mCRC who are administered FTD/TPI.
