April 2018 in “Journal of Investigative Dermatology” This study found that TGFbeta is a key pathway causing age-related loss of dermal fat's antimicrobial function, suggesting that targeting TGFBR might help restore skin defense against infections in older age.
December 2025 in “Animals” In this study on fine-wool sheep, researchers found that overexpressing the TGFBR1 gene decreased proliferation of dermal papilla cells by influencing multiple signaling pathways, suggesting TGFBR1 as a negative regulator in hair follicle development.
