Crosstalk Between Signaling Stroke Cascade and Therapeutic Receptors PPAR-γ, ROCK, CB1R, and CB2R: From Mechanism to Therapies.

Stroke remains a leading cause of disability and mortality worldwide, primarily due to the complex and multifaceted nature of its pathophysiology. This review aims to provide a comprehensive and mechanistic understanding of the crosstalk between key signaling pathways activated during stroke and the therapeutic potential of specific receptors: PPAR-γ, ROCK, CB1R, and CB2R. We delve into the intricate signaling cascades that occur post-stroke, including excitotoxicity, oxidative stress, and inflammation, highlighting the pivotal molecular players involved. PPAR-γ, known for its neuroprotective and anti-inflammatory properties, emerges as a critical modulator in stroke therapy. ROCK, a central component in the Rho/ROCK pathway, is implicated in vascular and neuronal damage, making its inhibition a promising therapeutic strategy. The roles of CB1R and CB2R within the endocannabinoid system are explored, with a focus on their dualistic nature in neuroprotection and neurotoxicity. The review further examines the interconnectivity of these receptors within the stroke signaling network, proposing that their synergistic modulation could enhance therapeutic outcomes. Current therapeutic approaches, including pharmacological and multi-target strategies, are critically evaluated, addressing the challenges in translating mechanistic insights into clinical practice. Additionally, the identification and utilization of biomarkers for stroke diagnosis and therapy monitoring are discussed, offering a glimpse into future prospects. Emerging therapies, novel drug developments, and personalized medicine approaches are presented as potential game-changers in stroke treatment.
