Mayo Clinic boosts immune system

Researchers at Mayo Clinic discovered that antiretroviral therapy (ART) can dramatically increase the production of disease-fighting T cells in non-HIV-infected individuals, including older adults. This finding has significant implications for developing new cancer vaccines and improving immune protection in vulnerable populations.

Mechanism regulating tooth shape formulation found

A recent study by researchers at the University of Helsinki has identified a key gene called ectodin that regulates tooth shape formation. The team found that mice lacking functional ectodin have abnormal teeth with broader cusps and extra teeth, highlighting the importance of ectodin in maintaining tooth development.
