Following cell damage, our body can react in different ways depending on the extent of the damage suffered. The first chance lies in the reversible effect of the reactions induced by the toxicants that come into contact with our body. The second opportunity, however, is to replace or modify the damaged parts. Finally, the third and final option is to eliminate all cells that have been severely compromised by the toxic effect.
Of course, the action that our organism carries out is different depending on the severity and the region of the body that has been hit. Most of the damaged cells die or are replaced with other new cells; if, on the other hand, the damage is at the tissue level. nervous, the cells are not replaced but are repaired.
Nerve cell repair takes place in several steps. In the first step cytokines are released as a consequence of the cleaning action carried out by the macrophages. In the second step the cytokines activate the glial cells (Schwann cells), which produce the nerve growth factor (Nervous Factor). In the third step the nerve growth factor allows the damaged cells to rebuild and regenerate a part of the cell, therefore the axon. The nerve cell without the axon could not in fact make contact with the other cells, so it could not even transmit a stimulus .
