TT-301
TT-301 is a small-molecule immunomodulator capable of penetrating the blood-brain barrier. TT-301 exerts neuroprotective effects by binding to IL-1β, downregulating STAT3 expression, and modulating the JAK-STAT signaling pathway, thereby inhibiting microglial activation and the release of proinflammatory mediators, and alleviating neuroinflammation and brain edema. TT-301 is used in research on traumatic brain injury, intracerebral hemorrhage, subarachnoid hemorrhage, muscle wasting and atrophy, and periodontal disease.

RNA extraction experimental
By lysing cells, releasing RNA, and removing impurities such as proteins and DNA, high-purity RNA products are finally obtained. The commonly used traditional method is the guanidine isothiocyanate/phenol/chloroform method (Trizol), which is suitable for a variety of animal materials including animal tissues, microorganisms, cultured cells, etc., and most plant materials.

Research Protocol for Neurological Diseases
PINK1/Parkin-mediated mitophagy pathway is a mitochondrial quality-control signaling axis in which mitochondrial depolarization stabilizes PINK1 on damaged mitochondria, activates Parkin recruitment and E3 ubiquitin ligase activity, promotes ubiquitination of outer mitochondrial membrane proteins, recruits selective autophagy adaptors, and drives lysosomal degradation of damaged mitochondria. In neurological disease research, this pathway is experimentally important because neurons, especially dopaminergic neurons, are highly dependent on mitochondrial integrity, and defective mitochondrial turnover can lead to mitochondrial dysfunction, oxidative stress, impaired neuronal survival, α-synuclein accumulation, and neuroinflammatory damage-associated signals. The genetic disease link is strongest in Parkinson’s disease because mutations in PRKN/parkin cause autosomal recessive juvenile parkinsonism, mutations in PINK1 cause hereditary early-onset Parkinson’s disease, and Drosophila studie

Pyroptosis Solutions
Pyroptosis is a lytic inflammatory cell-death pathway executed by gasdermin pores, most classically through inflammasome-mediated activation of caspase-1, cleavage of gasdermin D, membrane pore formation, LDH release, and secretion of IL-1β and IL-18. The canonical pathway is commonly modeled by priming cells with an inflammatory signal such as LPS to induce pro-IL-1β and inflammasome components, followed by an activation signal such as ATP or nigericin to activate NLRP3, ASC speck formation, caspase-1 cleavage, GSDMD cleavage, cytokine release, and pyroptotic membrane rupture. The non-canonical pathway is triggered when cytosolic LPS activates mouse caspase-11 or human caspase-4/5, leading to GSDMD cleavage and pyroptosis, and this can secondarily activate NLRP3-dependent IL-1β release. Pyroptosis is linked to inflammatory injury, infection, cancer, liver disease, ocular disease, placental inflammation, and other disease phenotypes, but unresolved questions include which gasdermin fam
