A Broad Application of CRISPR Cas9 in Infectious, Inflammatory and Neurodegenerative Diseases

Abstract

Being the most important immune-responsive cell type of the CNS, microglia always glorify the so-called crossroad of Neurology, Immunology and Pharmacology. As microglial activation is a hallmark of different neurodegenerative disorders including Alzheimer’s disease (AD), Parkinson’s disease (PD), HIV-associated neurocognitive disorders (HAND), Amyotrophic lateral sclerosis (ALS), etc., selective targeting of microglial cell signaling may be a valid option to control these neurodegenerative disorders with lesser side effects. This is particularly important as no effective therapies are available against these diseases and available neuroimmune modulators are known to target multiple cell types in a non-cell-specific manner. How we can achieve such specificity? A newly-developed cutting-edge molecular biology tool is rocking biomedical research in recent years so much so that it has already come under major lawsuits between the University of California Berkeley and the MIT-Harvard Broad Institute regarding its ownership rights, probably halting the Nobel committee to announce the most coveted prize to its owners. It is none other than Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR). In nutshell, the Cas9 enzyme has been paired with the bacterial immune system, CRISPR, to ultimately turn CRISPR/Cas9 as an effective genome editor. Therefore, this special issue has been devoted to highlight some of the recent discoveries on CRISPR/Cas9 in neurodegenerative disorders and explain these discoveries in the light of neuroimmune pharmacology.
