Multiple chemokine and growth factor receptors

The term Multiple chemokine and growth factor receptors refers to a diverse set of cell surface proteins, primarily G protein-coupled receptors (GPCRs) and receptor tyrosine kinases (RTKs), that mediate cellular responses to external stimuli (Source: Nature Reviews Drug Discovery, 2021). Chemokine receptors, such as CXCR4 and CCR5, primarily regulate leukocyte trafficking and immune cell recruitment, while growth factor receptors, including VEGFR, EGFR, and PDGFR, govern cell growth, survival, and blood vessel formation (Source: Pharmacological Reviews, 2018). These two classes of receptors often exhibit significant crosstalk, where chemokine signaling can transactivate growth factor receptors or vice versa, creating a robust network that promotes disease progression (Source: Journal of Clinical Investigation, 2019). In oncology, this synergy is exploited by tumors to promote metastasis and evade the immune system, while in fibrotic diseases, it drives the persistent activation of fibroblasts (Source: Cancer Cell, 2020). Therapeutic intervention often involves multi-kinase inhibitors or combination therapies designed to block multiple nodes within these pathways simultaneously (Source: FDA Label, Nintedanib). By targeting multiple receptors, these drugs aim to overcome the biological redundancy that often leads to resistance against highly specific single-target agents (Source: Science Signaling, 2022). However, the broad inhibition of these essential signaling pathways can lead to significant systemic side effects, necessitating careful patient monitoring (Source: Lancet Oncology, 2019).
