Tissue stress
Tissue stress (tissue adaptive syndrome) is an unspecific adaptive reaction universal for all tissues of adult organism which forms in tissue as a response to various external influences. The latter are tissue cells’ damage, overload of their specialized functions or regulatory influences.
==Tissue stress mechanism==
According to tissue adaptive syndrome (TAS) concept, this adaptive mechanism (see adaptation) comes into effect in damaged tissue (see Tissue (biology)) as a result of concurrence of two events. The first one is accumulation of TAS effectors in tissue (comutons, chalones, and contactins), which possess a unique feature of tissue specificity in their action on homologous tissue cells without species specificity. The second one is increase in sensitivity of damaged cells to these regulators, as it was demonstrated on the example of comuton. These effectors cause tissuespecific self-damage of homologous cells via disturbance of their ion homeostasis and energy-production processes. As a result, unspecific reaction to damage (CURD) is activated in the cells. This universal physiological reaction plays a role of TAS executive mechanism. Thus, the adaptive function of tissue stress is brought into action using such CURD properties as increase of cell unspecific resistance, as well as influence on the rate of cell metabolic processes. It is obvious that in the case of TAS these changes have to be tissuespecific, since they are initiated by way of cell self-damage under tissuespecific influence of TAS effectors.
As is well known the CURD consists of two phases. In the process of a slight damage of the cell the phase of metabolism stimulation is forming in it. When the cell is slightly damaged, it begins to form the phase of metabolism stimulation. Strong damaging influences initiate the CURD phase of metabolism inhibition in the cell.
According to the TAS concept, the protective effect of the tissue stress is realized in the case of forming of CURD metabolism stimulation phase by TAS effectors as a result of acceleration of reparative processes in the damaged cell. In the process of forming of CURD phase of metabolism inhibition by the above effectors the protective influence of tissue stress develops a result of cell reactivity decrease in response to the external damaging influences.
