Foetal defence against cancer: a hypothesis
It was once believed that the placenta blocks direct cell transfer between the mother and the foetus, that is, until the discovery of the maternal and foetal microchimerism which proved the existence of cell trafficking during pregnancy [1, 2]. It has been reported that 100% of the pregnant women at 36th week carry foetal cells in their circulation, the prevalence of which decreases, by 22–75%,...
متن کاملA social-network defence against whitewashing
We provide a defence against whitewashing for trust assessment mechanisms (TAM) by using an underlying social network in MAS and P2P. Since interaction requests are routed through the social network, routers can block requests from portions of the network known for whitewashing. Furthermore, by limiting feedback spread to the interaction routers, the trust assessment can be done without queryin...
متن کاملCooperation in defence against a predator.
The origin and the evolutionary stability of cooperation between unrelated individuals is one of the key problems of evolutionary biology. In this paper, a cooperative defence game against a predator is introduced which is based on Hamilton's selfish herd theory and Eshel's survival game models. Cooperation is altruistic in the sense that the individual, which is not the target of the predator,...
متن کاملAutophagy as a defence against intracellular pathogens.
Autophagy is a membrane trafficking pathway that results in the formation of autophagosomes which deliver portions of the cytosol to lysosomes for degradation. When autophagosomes engulf intracellular pathogens, the pathway is called 'xenophagy' because it leads to the removal of foreign material. Autophagy is activated during infection by Toll-like receptors that recognize pathogen-associated ...
متن کاملLung defence mechanisms against infection.
The respiratory tract must be open to the environment to allow exchange of gas between air and blood. This renders lhe lungs susceptible to colonization and infection by foreign organisms. It is necessary for lhe lower respiratory tract to have mechanisms to contain and control such foreign material. The gas exchange surface of lhe lung must be thin, delicate and permeable, rhus the mechanisms ...
