Does ligustrazine attenuate acute lung injury induced by blunt chest trauma?
Ligustrazine effectively protects lung injury induced by blunt chest trauma, and the protective effects seem to be mediated by attenuation of cell apoptosis via an increased ratio of Bcl-2/Bax and decreased caspase-3 activity.
Our results demonstrate that CD4+ CD25+(hi) Tregs from HBVHCC patients have decreased expression of PD1, resulting in higher IL-10 and TGF-β secretion. Increased suppressive ability of Tregs in HBV-related HCC confers increased anti-tumor suppressive response than in non-HBV-HCC. Modulation of Tregs and PD1 may serve as useful therapeutic targets.
