Background: TNF-α is a multifunctional proinflammatory cytokine and TGF-β1 is a secretory protein controlling epithelial proliferation and differentiation. Keratocyst presents an aggressive behavior and a growth mechanism different from that of radicular cyst. Aim: In this line, the present study aimed at evaluating TNF-α and TGF-β1 level and its association with histopath...

Background: Transforming growth factor-β1 (TGF-β1) has been found to play a crucial role in early central nervous system development. Several studies have illustrated decreased TGF-β1 levels in sera and brains of autistic children. Two point mutations in the TGF-β1 signal peptide at 869T/C and 915G/C have been reported to influence TGF-β1 expression. The aim of the pres...
