Stroke remains a leading cause of mortality and disability, with ischemic stroke being the most common type. It occurs due to reduced cerebral blood flow, cascade events initiated by oxygen nutrient deprivation, triggering excitotoxicity, oxidative stress, inflammation finally culminating in neuronal injury death. Key molecular players include glutamate receptors, acid-sensing ion channels, purinergic exacerbating cellular damage through calcium influx, mitochondrial dysfunction. Understanding these mechanisms has shaped therapeutic strategies, such as neuroprotective agents stem cell therapies. Current treatments tissue plasminogen activator (tPA) emphasize timely intervention, yet challenges persist patient-specific variability accessibility. This review provides an overview pathophysiology, emphasizing responses ischemia current future approaches including therapies aimed at mitigating stroke-induced disabilities improving long-term outcomes.

The extracellular matrix (ECM) plays critical roles in cytoskeletal support, biomechanical transduction and biochemical signal transformation. Tumor-associated macrophage (TAM) function is regulated by stiffness solid tumors often associated with poor prognosis. ECM stiffness-induced mechanical cues can activate cell membrane mechanoreceptors corresponding mechanotransducers the cytoplasm, modulating phenotype of TAMs. Currently, tuning TAM polarization through stimulation has received increasing attention, whereas its effect on fate rarely been summarized. A better understanding relationship between will contribute to development new strategies for cancer therapy. In this review, we first introduced overall stiffness, analyzed changes mediated tumor progression, finally summarized effects targeting prognosis provide insight into field.

Cannabinoids relieve pain, nausea, anorexia and anxiety, improve quality of life in several cancer patients. The immunotherapy with checkpoint inhibitors (ICIs), although very successful a subset patients, is accompanied by moderate to severe immune-related adverse events (ir-AE) that often necessitate its discontinuation. Because their role symptomatic relief, cannabinoids have been used combination immune inhibitor (ICI) immunotherapy. A few studies strongly suggest the use medicinal cannabis patients attenuates many ir-AE associated ICI increase tolerability. However, no significant beneficial effects on overall survival, progression free survival or relapses were observed; rather, some noted concurrent administration clinical benefits latter. cannabinoids' well documented immunosuppressive mediated through cannabinoid recptor-2 (CB2), we propose considering this receptor as an inhibitory per se. simultaneous neutralization CB2, treatment, may lead better outcomes receiving In regard, such cannabidiol (CBD) cannabigerol (CBG), little agonism for be therapeutic choices.
