Abstract This brief article highlights the results of Fu et al. (Proc Natl Acad Sci USA 119:e2204574119, 2022), who recently found that manganese (Mn) deficiency triggers long-lasting multicellular Ca 2+ oscillations in elongation zone (EZ) Arabidopsis roots and revealed a -CPK21/23-NRAMP1 axis as an important mechanism for plant tolerance adaptation to low Mn.
Campylobacter jejuni is a major worldwide cause of enteric illnesses. Adult immunocompetent mice are not susceptible to C. jejuni infection. However, we show here that mice deficient in the adaptor protein myeloid differentiation factor 88 (MyD88), which is required for signaling through most Toll-like receptors, can be stably colonized by C. jejuni but not by isogenic derivatives carrying muta...
in inflammatory diseases such as peri-implantitis (pi) and chronic periodontitis (cp) both adaptive and innate immunity play a part. natural resistance associated macrophage protein 1 ( nramp1 ) has considerable effects on macrophage function (phagocytosis) and host innate immune response against infections. the present study was to investigate the relationship of nramp1 gene polymorphisms with...
Natural resistance to infection with Salmonella typhimurium in mice is controlled by two major loci, Bcg and Lps, located on mouse chromosomes 1 and 4, respectively. Both Bcg and Lps exert pleiotropic effects and contribute to cytostatic/cytocidal activities of the macrophage. Bcg encodes for a membrane phosphoglycoprotein designated Nrampl (natural resistance-associated macrophage protein 1), ...
Brucellosis is a costly disease of water buffaloes (Bubalus bubalis). Latent infections and prolonged incubation of the pathogen limit the efficacy of programs based on the eradication of infected animals. We exploited genetic selection for disease resistance as an approach to the control of water buffalo brucellosis. We tested 231 water buffalo cows for the presence of anti-Brucella abortus an...
Macrophages are considered to be the mediators of resistance to extra-intestinal Salmonella infections. Nevertheless, the initial cellular response to Salmonella infections consists primarily of polymorphonuclear leukocytes (PMN). To determine whether PMN serve an important function for the infected host, we made mice neutropenic with the rat mAb to RB6-8C5 and infected them i.v. with approxima...
The mouse bcg host resistance gene is known to control the activation of host macrophages for killing of intracellular parasites like Leishmania donovani as well as intracellular bacteria, including Mycobacterium bovis BCG and Salmonella enterica serovar Typhimurium. The Nramp1 gene has been mapped to this locus and affects the efficiency of macrophage activation. It has been shown that imidazo...
In inflammatory diseases such as peri-implantitis (PI) and chronic periodontitis (CP) both adaptive and innate immunity play a part. Natural resistance associated macrophage protein 1 (NRAMP1) has considerable effects on macrophage function (phagocytosis) and host innate immune response against infections. The present study was to investigate the relationship of NRAMP1 gene polymorphisms with P...
Dictyostelium cells are forest soil amoebae, which feed on bacteria and proliferate as solitary cells until bacteria are consumed. Starvation triggers a change in life style, forcing cells to gather into aggregates to form multicellular organisms capable of cell differentiation and morphogenesis. As a soil amoeba and a phagocyte that grazes on bacteria as the obligate source of food, Dictyostel...
BACKGROUND & OBJECTIVES Association between polymorphisms in the natural resistance associated macrophage protein 1 (NRAMP1) gene and susceptibility to cutaneous leishmaniasis (CL) has been demonstrated worldwide; however, the reported results were inconsistent. This study aimed to determine the association of NRAMP1 variants with susceptibility to CL infection and patients' response to treatme...
