| Immunopharmacology Comments |
| Accumulating evidence suggests that loss-of-function mutations or deletion of PTEN is an immune evasion mechanism exploited by tumour cells [5], and that disrupted PTEN activity may have implications for resistance to T cell-mediated immunotherapy (checkpoint blockade) [2,4]. |

| General Comments |
| PTEN's phosphatase activity dephosphorylates phosphatidylinositol (3,4,5)-trisphosphate (PtdIns (3,4,5)P3 or PIP3) to PIP2 (which leads to inhibition of the AKT signaling pathway), and it also appears to have some protein phosphatase activity. PTEN acts as a tumour suppressor. Inactivation of PTEN expression (by mutation or deletion) is one of the most common oncogenic pathways identified in human cancers. PTEN mutations have also been identified in non-cancerous neoplasia (e.g. hamartomas) [3,6-7]. |
