Parkinson's Disease (PD) is a neurodegenerative disease that involves loss of neurons in the substantia nigra, leading to effects such as bradykinesia, akinesia, resting tremor, muscular rigidity, gait and postural instability, and cognitive disabilities later. An animal model widely used to study the DP is the model that uses the direct administration of 6-OH-dopamine (6-OHDA) in the medial forebrain bundle or the striatum, this drug being responsible for the destruction of dopaminergic neurons selectively. There is evidence that some cellular communication systems can modulate the development of PD. For example, kinins, acting on B1 and B2 receptors may be involved in neuroprotection. Another type of receptor that may be involved in Parkinson purinergic receptors are activated by adenosine or ATP (P2 and P1 receptors). Also, receptors that have been associated with neurodegeneration channels are transient potential (TRPS) which are divided into subtypes such as TRPV, TRPM, TRPC, and TRPML TRPP. Taking into account the effects of these receptors on cells of the nervous system, this paper aims to evaluate the expression and involvement of these membrane receptors in PD induced by 6-OHDA in mice strain C57Bl/6 and knockout receptors B1, B2, TRPM2 and TRPM7. Moreover, agonists/antagonists of these receptors are also used to assess the issue, hoping that those molecules are involved in PD, playing possible protective action of the disease. For that techniques will be used as immunohistochemistry, Western blot and real-time PCR, which can generate relevant data toward the development of therapeutic strategies.
