The zombie parasite" cats can cause cancer and diseases of a brain at the person - RIA Novosti, 9/13/2017
MOSCOW, 13 Sep — RIA Novosti. Infection of the person with toxoplasma — the parasite of cats turning mice into "zombie" — has been connected with the increased probability of development of epilepsy, Alzheimer and Parkinson's diseases and some types of cancer of brain, it is told in article published in the Scientific Reports magazine. "We assume that development of these diseases affects a set of different factors. One of them is the parasite and those genes which he activates in the infected brain, protecting himself from attention of immune system. Pregnancy, a stress, other infections and bad microflora can act as other risk factors. If a part of these factors coincides, then there can be one of brain diseases" — Rima McLeod from the University of Chicago (USA) tells. © Photo: Wendy Ingram, Adrienne Greeneuchenye have found out how "zombie" - the parasite of cats operates a brain of a chelovekatoksoplazm (Toxoplasma gondii) — the intracellular parasite who is usually living in intestines of domestic cats. Today, by estimates American CDC, are infected by him over 60 million residents of the USA. The prevalence of this pathogen among pets and their owners has forced scientists to pay attention to it. It has turned out that toxoplasma is capable to change behavior of the owner, causing irreversible changes in work of a brain. She does mice and a chimpanzee fearless at a look and a smell of cats and leopards, and people — inclined to a suicide and irrational acts and also inexplicable attacks of rage. Besides, toxoplasma can cause the most serious defects in development of a fruit in the pregnant woman and lead to an abortion. McLeod and her colleagues have found out that hit of this parasite who was considered as rather harmless earlier in a brain of the person can lead to development of very serious problems. For this purpose scientists have studied what changes in work of a brain are caused by Toxoplasma gondii, and have analysed as often possible consequences of these changes occur among the healthy and infected people. © AP Photo/dpa Julian Stratenschultebiologi have found a security measure of the person from "zombie parasite" кошекВ it him the fact that the University of Chicago for nearly forty years watched life about three hundred families which members have been infected with toxoplasmosis has helped. It has allowed scientists to understand how the parasite can influence development of the problems with health connected with work of a brain. As these observations, toxoplasma have shown, getting into a brain, changes work of several tens genes, suppressing part of them and strengthening work of other sites of DNA. Almost all these genes or operate work of congenital immune system, or conduct various processes connected with growth of stem cells and new fabrics. The cat's parasite suppresses work of the first group of genes that helps him to survive, and stimulates work of the second set, providing himself with food. Both doesn't pass completely for the infected person as easing of immunity makes him more predisposed to development of cancer and neurodegenerate diseases, connected
