Administration of recombinant IL-21 enhances Aβ deposition in the brains of 5xFAD mice. Mice were given five injections of IL-21 or four injections of anti-IL-21R antibody (IL-21R blocker) and Aβ plaques were stained in the brain using thioflavin-S. Accumulation of plaques in—A vehicle-injected control; B IL-21 injected; C IL-21R blocker injected; D bar graph depicts the quantitation of the same in both males and females. N = 14
