Regulace translace během imunitních reakcí.

Hlaváček, Adam

Immune reaction often requires a prompt modification of gene expression that in turn alters cellular physiology. There are an increasing number of articles supporting a critical role of translational control in this aspect of cellular biology. The aim of this work is to present some of cellular and molecular mechanisms that connect translational control and immune reaction in immune and somatic cells and can be possibly misused by some viruses. Perhaps not surprisingly, many immunologically relevant translational control mechanisms are similar to those acting during the stress response. Over the years it has been documented that the T cells, dendrocytes, Natural killer cells and macrophages utilize translational control for their immunological activation following stimulation. Combination of general and gene-specific translational control mechanisms enables fast changes in proteome and physiology that are characteristic for immune cell activation. The overall impact of translational control on immune response is further illustrated by the fact that it acts upon each stage of life of immune cells - from their activation, through survival, to a programmed cell death. Even in some non-immune cells the translational control plays an important role with respect to immunity, as these cells are known to have an...
