Tau protein is found in abundance in neurons of the central nervous system. This protein is a product of microtubule-associated protein tau (MAPT) gene, that is located on chromosome 17. It is associated with pathologies of several nervous system disorders, such as dementia, Parkinson’s disease, and Alzheimer’s disease.
Spleen tyrosine kinase (Syk) is a protein that belongs to the family of tyrosine kinases with an ability to initiate the inflammatory responses, by connecting immune cell receptors to intracellular signaling pathways.
RNA interference (RNAi) is a molecule type that silences the gene and limits the transcription of the mutated gene. Gene silencing is a novel mechanism that inactivates the transcripts of mutated gene, by activating sequence specific RNA degradation process.
Rho kinase inhibitor, also known as ROCK inhibitor, inhibits the rho kinases, a family of small GTP-binding protein. Rho kinases are found to regulate cell motility, proliferation, shape, gene expression, apoptosis, and are also involved in the signalling pathway.

Nav1.7 voltage-gated sodium channel inhibitors are the drug candidates that target the sodium channels Nav1.7 and have been significant in pain management. The sodium channels Nav1.7 receptors are generally found in two types of neurons: nociceptive pain neurons, such as trigeminal neurons and dorsal root ganglion; and sympathetic ganglion neurons which form a part of the autonomic (involuntary) nervous system. These receptors play an important role in generation and conduction of action potential.
