DL001 reduces the immunosuppressive effects of mTOR inhibition compared to rapamycin, specifically preserving more T cell and Treg populations.

This study shows that DL001, a selective mTORC1 inhibitor, causes less suppression of T cells and T regulatory cells than standard rapamycin in mice. This suggests that future human applications of selective mTOR inhibitors might have a better safety profile regarding immune function and infection risk, though human trials are needed to confirm this.

In contrast, DL001 had a significantly smaller effect on total T cell and helper T cell numbers, reducing the number of CD3+ cells and CD3+CD4+ cells by 13% and 23%, respectively... rapamycin reduced total CD3+ (T) cell numbers by 40%, and CD3+CD4+ (helper T) cell numbers by 47%.
