Involvement of the Purinergic System in Cell Death in Models of Retinopathies
Literature data demonstrate already that the presence of adenine nucleotides in the extracellular environment induces cell death that leads to several retinopathies. As said, the objective is to carry out a systematized review of the last decade, relating purinergic signaling to the outcome of cell death and retinopathies. It is possible to identify different mechanisms that occur through the activation of purinergic receptors. The exacerbated activation of the P2X7 receptor is mainly involved in the apoptotic death pathway, and this response is due to the dysregulation of some components in the intracellular environment, such as the Ca2+ ion, CD40, MiR-187, and influence of mononuclear macrophages. The A2A receptor is involved in increasing levels of cytokines and promoting inflammatory processes. The data presented can be used as a basis to better understand the mechanisms of death in retinopathies, in addition to proposing therapeutic strategies with the potential to be transposed to several other models.
