Is Cytoplasmic PTEN a Specific Target for Neuronal Survival

The differential sensitivity of neurons to phosphatase and tensin homolog’s (PTEN) lipid and protein phosphatase actions pose difficulties in defining the exact neuronal phenotype generated by targeting PTEN in neuronal injury. PTEN’s biology beyond its phosphatase functions are also emerging. Considering spatial dynamics of PTEN a decisive factor for its mode of action we propose selective targeting of its cytoplasmic fraction a better therapeutic approach in neuronal injury.
