Leishmania promastigotes evade interleukin 12 (IL-12) induction by macrophages and stimulate a broad range of cytokines from CD4+ T cells during initiation of infection. [PDF]

open access: yes, 1994
Leishmania major are intramacrophage parasites whose eradication requires the induction of T helper 1 (Th1) effector cells capable of activating macrophages to a microbicidal state.

5'-nucleotidases, nucleosides and their distribution in the brain: pathological and therapeutic implications [PDF]

open access: yes, 2013
Elements of the nucleoside system (nucleoside levels, 5'-nucleotidases (5'NTs) and other nucleoside metabolic enzymes, nucleoside transporters and nucleoside receptors) are unevenly distributed in the brain, suggesting that nucleosides have region ...
