In one study, loss of TAFA2 in knockout mice led to significant neuronal reduction and increased apoptosis in the brain, correlating with deficits in spatial learning, memory, and alterations in emotional behaviors. These changes were mechanistically linked to the downregulation of key pathways such as PI3K/Akt and MAPK/Erk, as well as reduced expression of CREB target genes including BDNF, c-fos, NF1, and CBP, highlighting a critical role for TAFA2 in maintaining neuronal integrity and activity."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": ""}, {"type": "p", "children": [{"type": "t", "text": "\nAn additional study further underscores the importance of TAFA2 by illustrating its anti‐apoptotic function in neuronal cells.
