Introduction: The p38 serine-threonine kinases are members of the large family of mitogen-activated protein kinases (MAPK). In particular, p38 MAPK subgroup includes four isoforms (α, β, γ, δ), among which p38α and p38β are mainly involved in inflammatory disorders. Indeed, by activating key transcription factors and by inducing the expression of several cytokines and chemokines, p38α plays a central role in the pathobiology of chronic obstructive pulmonary disease (COPD).Areas covered: This concise review focuses on the contribution of p38 MAPK to development, maintenance, and amplification of chronic lung inflammation in COPD. Moreover, we discuss the potential role of p38 MAPK as suitable target for perspective therapeutic approaches under evaluation as potential new COPD treatments. In this regard, an extensive literature search has been conducted throughout PubMed source (1990-2020).Expert opinion: Despite some promising preclinical data, so far the results of clinical trials evaluating p38 MAPK inhibitors have been quite disappointing, thus suggesting a cautious judgment about the future perspectives of these drugs for COPD therapy.
