Is mass distribution of azithromycin for trachoma control associated with short-term reduction in risk of acute lower respiratory infection in young children?
Mass distribution of a single dose of oral azithromycin for trachoma is associated with a significant short-term reduction in ALRI morbidity among young children.
In conclusion, human to pig cell-mediated cytotoxicity was mediated predominantly by CD4+ T cells through the Fas/FasL pathway of apoptosis. These results suggest that direct cytotoxicity by xenoreactive CD4+ T cells may be one of several effector mechanisms involved in cellular xenograft rejection.
