TLDR
In this article, the authors discuss the origin and development of macrophages and their role in the intestinal inflammatory response or infection, and their effects on the development of inflammatory bowel disease (IBD) and its role in inducing fibrosis, activating T cells, reducing colitis, and treating intestinal inflammation.Abstract:
Macrophages, which are functional plasticity cells, have the ability to phagocytize and digest foreign substances and acquire pro-(M1-like) or anti-inflammatory (M2-like) phenotypes according to their microenvironment. The large number of macrophages in the intestinal tract, play a significant role in maintaining the homeostasis of microorganisms on the surface of the intestinal mucosa and in the continuous renewal of intestinal epithelial cells. They are not only responsible for innate immunity, but also participate in the development of intestinal inflammation. A clear understanding of the function of macrophages, as well as their role in pathogens and inflammatory response, will delineate the next steps in the treatment of intestinal inflammatory diseases. In this review, we discuss the origin and development of macrophages and their role in the intestinal inflammatory response or infection. In addition, the effects of macrophages in the occurrence and development of inflammatory bowel disease (IBD), and their role in inducing fibrosis, activating T cells, reducing colitis, and treating intestinal inflammation were also reviewed in this paper.read more

Astragaloside IV Alleviates the Experimental DSS-Induced Colitis by Remodeling Macrophage Polarization Through STAT Signaling.
Lianlian Tian,Jun-Long Zhao,Jian-Qin Kang,Shibo Guo,Nini Zhang,Lei Shang,Ya-Long Zhang,Jian Zhang,Xun Jiang,Yan Lin +9 more
TL;DR: Wang et al. as mentioned in this paper found that Astragaloside IV attenuated clinical activity of DSS-induced colitis that mimics human IBD and resulted in the phenotypic transition of macrophages from immature pro-inflammatory macrophage to mature pro-resolving macophages.

TL;DR: In this article , metabolic alterations underlie intestinal macrophage phenotype and function during IBD, and how microenvironmental cues trigger their metabolic reprogramming processes, and also summarized potential therapeutic approaches for IBD by manipulating cellular metabolism of macrophages.

TL;DR: The first formal description of the microbicidal activity of extracellular traps (ETs) containing DNA occurred in neutrophils in 2004 and since then, ETs have been identified in different populations of cells involved in both innate and adaptive immune responses as mentioned in this paper.

Synovial Macrophage and Fibroblast Heterogeneity in Joint Homeostasis and Inflammation
TL;DR: This review summarizes the current understanding of the phenotypic and molecular characteristics of resident synovial macrophages and fibroblasts and highlights their crosstalk during joint homeostasis and joint inflammation, which is increasingly appreciated as vital to understand the molecular basis of prevalent inflammatory joint diseases such as rheumatoid arthritis.

Polyethylene terephthalate nanoparticles effect on RAW 264.7 macrophage cells
J. Cristobal Aguilar-Guzmán,Katarzyna Bejtka,Marco Fontana,Eugenia Valsami-Jones,Anaid Meza Villezcas,Rafael Vazquez-Duhalt,Ana G. Rodríguez-Hernández +6 more
TL;DR: In this paper , the effect of PET nanoparticles (PET-NPs) (≤ 250 d.nm) was assayed on mouse macrophages cell line (RAW 264.7) in in vitro experiments, and the results showed that 15 μg/mL of nanoparticles concentration had exhibited effects in cell proliferation and a slightly increased production of reactive oxygen species (ROS), which seems to trigger cell response as foreign particles related to upregulation of PCDH12, IGH-V10, ROBO1 genes, and cell maintenance functions, related to FTSJ2 gene upregulation.

Exploring the full spectrum of macrophage activation.
TL;DR: This Review suggests a new grouping of macrophages based on three different homeostatic activities — host defence, wound healing and immune regulation, and proposes that similarly to primary colours, these three basic macrophage populations can blend into various other 'shades' of activation.

TL;DR: Recent evidence suggests that differential modulation of the chemokine system integrates polarized macrophages in pathways of resistance to, or promotion of, microbial pathogens and tumors, or immunoregulation, tissue repair and remodeling.

TL;DR: A set of standards encompassing three principles-the source of macrophages, definition of the activators, and a consensus collection of markers to describe macrophage activation are described with the goal of unifying experimental standards for diverse experimental scenarios.

Unravelling the pathogenesis of inflammatory bowel disease
TL;DR: Recently, substantial advances in the understanding of the molecular pathogenesis of inflammatory bowel disease (IBD) have been made owing to three related lines of investigation as mentioned in this paper, which have shown the importance of epithelial barrier function, and innate and adaptive immunity in disease pathogenesis.
