1 These chronic conditions compromise the immune system by impairing the neutrophil function as well as T-cell-mediated immunity.

When the extent of CD4 T-cell-mediated immunity before and after seasonal influenza vaccination was compared in the healthy donors enrolled in the study, a nonhomogeneous pattern of responses was detected (online Appendix Figure; available from www.

Our results suggest that exposing young calves to live BVDV while maternal antibodies are present generates T-cell-mediated immunity to BVDV," says Ridpath.

The low-fat diet enhanced T-cell-mediated immunity in older people with elevated low-density lipoprotein (LDL-cholesterol) levels.

Our study demonstrates that more than 90% of volunteers maintain measurable humoral or T-cell-mediated immunity for up to 75 years after smallpox vaccination--a result that will affect future models of potential smallpox outbreaks in contemporary populations.
