Description

The Adenosine Triphosphatase (ATPase), which is found on the membrane, reversibly connects protons moving across the membrane to the flow of anhydro-bond equivalents between water and the couple Adenosine Triphosphate (ATP)/ (Adenosine Diphosphatase (ADP)+Pi); that during oxidative reduction, the respiratory chain, which is positioned on the membrane, catalyses the flow of reducing equivalents by linking reversibly the translocation of protons across the membrane with the flow of reducing equivalents; the transit of important metabolites is permitted without the membrane potential collapsing because the mitochondrial inner membrane possesses particular carriers that are ions, allows anion-OH^- and cation-H⁺ exchanges that regulate the pH and osmotic difference across the membrane. Moreover, a particular coupling membrane with a low permeability to protons as well as to anions and cations in general houses the systems of the first three postulates. The fourth postulate was incorrectly and commonly understood to imply that the inner membrane lacked cation channels. Given this viewpoint, which was prevalent even in the 1990s, it is not surprising that the PTP, with an estimated diameter of 3 nm, did not pique the bioenergetics community's curiosity. Since the discovery that the inner mitochondrial membrane does, in fact, contain cation channels that are expectedly tightly regulated and that a PT can occur in cells, tissues, and organisms where it plays a role in cell death and may even be involved in Ca2+ homeostasis. A voltage-dependent channel that crosses the cytoplasm, Outer Mitochondrial Membrane (OMM), Inner Mitochondrial Membrane (IMM), and mitochondrial matrix is known as the Mitochondrial Permeability Transition Pore (MPTP) complex. It is made up of numerous proteins and is both non-specific and selective.

The mammalian Mitochondrial Permeability Transition Pore (MPTP), located between the mitochondrial inner and outer membranes, is a non-specific pathway for signal transduction or material transfer between the mitochondrial matrix and cytoplasm, including the upkeep of Ca²⁺ homeostasis, control of oxidative stress signals, and protein translocation induced by some stimuli. It has been demonstrated that ongoing MPTP opening causes ischemic stroke patients' neurons to undergo apoptosis. The therapy of ischemic stroke has demonstrated excellent efficacy when MPTP over opening-induced apoptosis is inhibited. Researchers have also gradually unveiled the probable molecular pathways of pharmacological therapy for stroke. It is also possible to treat stroke from the standpoint of mitochondrial MPTP. The properties of multi-components or multi-targets for ethnic medicines. Due to the benefits listed above, it is essential that we investigate and clarify the novel ethnic medical perspective on stroke treatment as well as identify the precise molecular mechanisms using cutting-edge technologies. We were delighted to recognize balanced mitochondrial MPTP as a cutting-edge approach to the medical management of stroke.

Conclusion

We investigate the relationship between abnormal MPTP opening and neuronal death in ischemic stroke. We also included a list of currently authorized drugs, prescriptions for herbal remedies, found monomer compounds, and traditional medications from different cultures for reducing MPTP over opening-induced ischemic neuron death. Finally, we aim to provide a new perspective and insight for ethnic medicine in the prevention and treatment of stroke by decreasing MPTP over opening-induced neuronal death.
