Exploring the role CD163-labeled TAMs and FOXP3-labeled Tregs in different types of breast cancer: Reflections and putative benefits

Indian Journal of Pathology and Microbiology, 2021
Context: Tumor immune microenvironment (TIME) is heterogeneous and dynamic. It exerts bimodal pro and antitumor effects. Among the TIME contributors, TAMs and Tregs are condemned as cancer cells allies rather than enemies; however, such contribution is ...

Mycobacterium tuberculosis Methyltransferase Rv1515c Can Suppress Host Defense Mechanisms by Modulating Immune Functions Utilizing a Multipronged Mechanism

Frontiers in Molecular Biosciences, 2022
Mycobacterium tuberculosis (M. tb) gene Rv1515c encodes a conserved hypothetical protein exclusively present within organisms of MTB complex and absent in non-pathogenic mycobacteria.

Cyclophosphamide abrogates the expansion of CD4+Foxp3+ regulatory T cells and enhances the efficacy of bleomycin in the treatment of mouse B16-F10 melanomas

Cancer Biology & Medicine, 2021
Objective: Promotion of the proliferative expansion of CD4+Foxp3+ regulatory T cells (Tregs) is one of the side effects that limits the use of bleomycin (BLM) in the treatment of tumors. In this study, we examined the hypothesis that cyclophosphamide (CY)

HMGB1 Signaling-Mediated Tumor Immunity in Cancer Progress

Frontiers in Bioscience-Landmark, 2023
Tumor immunity is a cycle that begins with the release of antigens from tumor cells and ends with the destruction of tumor cells. High mobility group box 1 (HMGB1) is a nonhistone protein widely present in the nucleus of mammalian cells and can be ...

VIP Promotes Recruitment of Tregs to the Uterine–Placental Interface During the Peri-Implantation Period to Sustain a Tolerogenic Microenvironment

Frontiers in Immunology, 2020
Uterine receptivity and embryo implantation are two main processes that need a finely regulated balance between pro-inflammatory and tolerogenic mediators to allow a successful pregnancy.

Vancomycin-induced gut microbiota dysbiosis aggravates allergic rhinitis in mice by altered short-chain fatty acids

Frontiers in Microbiology, 2022
ObjectiveThis study aims to explore how gut microbiota dysbiosis affects allergic rhinitis (AR) and whether short-chain fatty acids (SCFAs) play a role in this process.MethodsA mouse gut microbiota dysbiosis model was established by adding vancomycin to ...
