The signifikance of extrapituitary prolactin and innate immune reaction in severe immunopathological conditions.
Chromá, Věra ; Daňková, Pavlína (advisor) ; Gabalec, Filip (referee)
Introduction: Communication between neuroendocrinne and immune system is arranged by hormones and cytokines in endocrinne, paracrinne and autocrinne manner. One of the factors involved is also prolactin, a pituitary hormone and an immune cytokine. Sepsis is a system reaction to inflammation mediated by Th1 immune response, which is supported by prolactin as well. Primary protection against sepsis is mediated by innate immunity. Toll- like receptors distinguish molecules, which are connected with pathogens. Afterwards this identification of a specific pathogen toll-like receptors trigger immune reaction with the main goal of destroying this pathogen and also with the goal of renewing the balance of the organism. It is supposed that in the organism that is hardly attacked by a pathogen, the PRL, TLR2 and TLR4 gene expression is on the increase. We studied the levels of PRL, TLR2 and TLR4 mRNA production in circulating monocytes derived from septic patients. Simultaneously, the effect of PRL -1149 G/T SNP on physiological levels of PRL mRNA and its expression in the course of sepsis was evaluated. Materials and methods: As a source of monocytes, blood specimens from 43 septic patients and 40 healthy controls were used. The blood of septic patients was taken three times with some time difference and...
