Macrophages are a critical member of the innate immune system and can intensify tumor invasiveness and assist the growth of neoplastic cells. Moreover, they have the capability to reinforce immunosuppression and angiogenesis. Various investigations suggest that health-related issues, including inflammatory disorders and neoplastic diseases may be caused by environmental toxicant exposure. However, it is still unclear what role these environmental toxicants play in causing carcinogenesis by disturbing the mechanisms of migration, polarization, differentiation, and immune-stimulatory functions of macrophages. Accordingly, in this article, we will explore the interaction between environmental chemicals and inflammatory macrophage processes at the molecular level and their association with tumor progression and carcinogenesis.

Background: A secondary Pasteurella multocida (Pm) infection following Mycoplasma ovipneumoniae (Mo) challenge in sheep results in severe respiratory disease. Scavenger receptor A (SRA) is a key phagocytic receptor on macrophages, which facilitates microbial clearance. However, the role of sheep SRA in Mo-associated secondary Pm infection is less understood.

Objective: Adipose-derived regenerative cells (ADRCs) are promising cell sources for damaged tissue regeneration. The efficacy of therapeutic angiogenesis with ADRC implantation in patients with critical limb ischemia has been demonstrated in clinical studies. There are several possible mechanisms in this process such as cytokines and microRNA.

Recent studies have shown that the glymphatic system plays a crucial role in driving hyperacute edema after ischemic stroke. This has sparked interest in understanding how this system changes in later phases of ischemic stroke. In this study, we utilized cisternal contrast-enhanced magnetic resonance imaging (CE-MRI) and immunofluorescence staining to investigate glymphatic system alterations at subacute and chronic phases of ischemic stroke.

Background And Aims: Hepatocellular carcinoma (HCC) has a poor prognosis and limited treatment options. TGF-β is a promising therapeutic target, but its dual role, as both a tumour suppressor and promoter, complicates its clinical application. While its effects on tumour cells are increasingly understood, its impact on the tumour stroma remains unclear.

Immune-related factors may serve an important role in the development of endometriosis, considering the occurrence of substantial abnormalities in the immune system of women with endometriosis, including reduced T-cell reactivity and natural killer cell cytotoxicity, as well as increased numbers and activation of peritoneal macrophages. Moreover, women suffering from endometriosis are at a higher risk for developing various autoimmune diseases as comorbidities of endometriosis. Recent epidemiological data demonstrate that patients with endometriosis have a significantly higher risk (2.
