Abstract

The multifunctional cytokine tumour necrosis factor-alpha (TNF) displays many physiological effects in a variety of tissues, especially proliferative and cytotoxic actions in immunological cells. Recently, we uncovered an important new mechanism by which TNF can sensitise airway smooth muscle (ASM) to a fixed intracellular Ca2+ concentration which in vivo would produce a marked hypercontractility of the airways. Here, we report that both 50-60 kDa type I TNFR (TNFR1) and 70-80 kDa type II TNFR (TNFR2) receptor subtypes were expressed in ASM cells and selectively activated the stress kinases, c-Jun N-terminal kinase and p38 mitogen-activated protein kinase (p38 MAPK), However, TNF caused no activation of p42/p44 MAPK or cytosolic phospholipase A(2) activity. In contrast, TNF stimulation of the TNFR1, but not the TNFR2, elicited nuclear factor-kappaB transcription factor function, a species known to be important in mediation of certain inflammatory cellular responses. This is the first report of TNF receptor subtypes in ASM cells causing selective kinase activation, which may prove important in therapeutic strategies for treating immune airway disorders such as chronic obstructive pulmonary disease and asthma.
