    immune cells that activate macrophages to fight intracellular pathogens

    T helper 1 cells, often abbreviated as Th1 cells, are a type of immune cell that play a crucial role in the body's defense against intracellular pathogens like viruses and certain bacteria. They produce cytokines, such as interferon-gamma (IFN-γ), which activate macrophages and enhance the ability of other immune cells to destroy infected cells.
