Prolactin-cytokine network in the defence against Acanthamoeba castellanii in murine microglia [corrected].

In the central nervous system, cytokine-primed microglia play a pivotal role in host defence against parasite infections. In this study, the effect of recombinant (r) prolactin (rPRL) and rIFN-gamma on A. castellanii infection in murine microglia was examined.

Complex network of cytokines activating murine microglial cell activity against Acanthamoeba castellani.

In the central nervous system, cytokine-primed microglia play a pivotal role in host defence against Acanthamoeba castellani infections. In this study, the effect of rIL-1beta, rIL-6 or rTNF-alpha, combined or not with rIFN-gamma, on A. castellani infection of murine microglia was examined.

Effect of protein SV-IV on experimental Salmonella enterica serovar Typhimurium infection in mice.

Seminal vesicle protein IV (SV-IV) is a secretory anti-inflammatory, procoagulant, and immunomodulatory protein produced in large amounts by the seminal vesicle epithelium of the rat under the strict transcriptional control of androgen. In particular, this protein was shown to possess the ability to markedly inhibit in vivo the humoral and cell-mediated immune responses of mice to nonbacterial cellular antigens (sheep erythrocytes and spermatozoa). We report data that demonstrate that in mice treated with SV-IV and infected with Salmonella enterica serovar Typhimurium, SV-IV is able to downregulate some important immunological and biochemical parameters that serovar Typhimurium normally upregulates in these animals.
