Background: Leishmania is an intracellular protozoan parasite that enters and reproduces in macrophage cells. Macrophages are important immune cells phagocyte many pathogens such as bacteria, fungi, parasites spp. but incapable of killing this parasite, living the phagosomes infected macrophages, multiplying, resulting divesting macrophages appearance lesions. Many present drugs for treatment h...

Th1 lymphocytes produce cytokines such as IL-2, IFN-γ, and TNF-α, TNF-β and GM-CSF and play an important role in the increase of delaying sensitivity and defense against intracellular pathogens. IFN-γ is the most important Th1 cell cytokine that induces the production of IgG, activation of macrophages,enhancing phagocytosis, and also increasing MHC class I and class II mo...

Wound healing disorders including diabetic ulcers, chronic venous leg ulcers and pressure are still remains uncured pose a stern challenge to health care system. Accumulation of dysfunctional macrophages over time have been identified as major underlying cause for wounds, however molecular events regulating these unclear. In present study, we found that histone H3K27 acetylation, an epigenetic ...

objective: the brucella melitensis virb operon, encoding a type iv secretion system (t4ss), is required for intracellular replication and persistent infection in the mouse model. the product of the second gene of the virb operon, virb2, is predicted to be localized at the bacterial surface, where they could potentially interact with host cells. studies to date have focused on characterization o...

background: the water-soluble extract of ganoderma lucidum (reishi) has been used as an immunomodulator to stimulate spleen cells proliferation and cytokine expression. objective: to investigate the effect of ganoderma lucidum (g. lucidum) on cytokine production by mice peritoneal macrophages. methods: mice peritoneal macrophages were prepared by intra-peritoneal injection of 5 ml cold pbs. per...

59Fe-labelled human lactoferrin was found to be preferentially ingested by mouse alveolar macrophages (MAM) when compared to 59Fe-labelled human transferrin. The cells bound and ingested 125I-labelled iron-saturated and iron-free lactoferrin. The latter was digested faster (t1/2 = 5.8 hours), however, than the iron-saturated compound (t1/2 = 10.5 hours). The constant elimination of the Fe-lacto...

Dr. Martin is the recipient of Research Career Development Award K04-AI-70335 from the National Institutes of Health. Received for publication 18 April 1977 and in revised form 24 June 1977. and lymphocytes from individual patients was also positively correlated (r = 0.889, P < 0.001 for nonsmokers and r = 0.942, P < 0.001 for smokers). These results indicate that the capacity for aryl hydrocar...

Macrophage polarization is influenced by lipids, which also exert significant control over macrophage functions. Lipids and their metabolites are players in intricate signaling pathways that modulate macrophages’ responses to pathogens, phagocytosis, ferroptosis, inflammation. This review focuses on lipid metabolism functions addresses potential molecular targets for the treatment of macrophage...
