Targeting MAPK signaling: A promising approach for treating inflammatory lung disease

The extracellular signals that initiate intracellular reactions are dispatched by the mitogen-activated protein kinases (MAPKs), which oversee a multitude of cellular activities. p38, Extracellular signal-regulated kinase (ERK), and c-Jun NH2-terminal kinase (JNK) are members of the vertebrate family of MAPKs, and each MAPK signaling pathway consists of a MAPK kinase (MAP3K), a MAPK kinase (MAP2K), and a MAPK. These signaling pathways orchestrate numerous cellular processes, including cell growth, survival, differentiation, and apoptosis. The emergence of various inflammatory respiratory diseases in humans has been linked to the dysregulation of MAPK signaling pathways. Conditions such as asthma, lung cancer, pulmonary fibrosis, and COPD are among the prevalent respiratory ailments where MAPK plays a pivotal role. Additionally, MAPK is implicated in infectious diseases, including COVID-19, pneumonia, and tuberculosis. COPD, asthma, emphysema, chronic bronchitis, and other inflammatory lung disorders highlight the significance of MAPK as a potential target for therapeutic development. Further studies are needed to delve into the molecular mechanisms by which the MAPK signaling pathway contributes to inflammatory lung disorders, representing an area that demands continued research.
