DP1 prostanoid receptor activation increases the severity of an acute lower respiratory viral infection in mice via TNF-a-induced immunopathology.

Abstract

T cells), and the heightened production of the pro-inflammatory cytokines TNF-a, IL-6, and IL-1ß. These phenotypes, as well as the increased mortality, were significantly attenuated following the administration of anti-TNF-a to PVM-infected, BW245c-treated mice. In summary, pharmacological activation of the DP1 receptor in PVM-infected neonatal mice boosts antiviral innate and adaptive immunity, however, this is ultimately detrimental, as a consequence of increased TNF-a-induced morbidity and mortality.
