Low density lipoprotein receptor related protein 1 (LRP1) is a type I transmembrane receptor that mediates the endocytosis of various ligands, including apolipoproteins and tau. Both proteins are genetically and pathologically linked to Alzheimer's disease (AD).Postsynaptic Density protein 95 (PSD95) is a member of the membrane-associated guanylate kinase (MAGUK) family of proteins that functions as a scaffolding protein to promote assembly and function of the postsynaptic density complex .

Apoptosis is a strictly regulated process that leads to orderly cell breakdown and clearance. Unlike necrotic cell death, apoptosis is well regulated and plays a critical role in development, immune function, and tissue homeostasis. Normal cells undergo apoptosis when subjected to various endogenous and exogenous stimuli to maintain a balance between cell survival and death.

Akt (also known as PKB or Rac) plays a critical role in regulating cell survival and apoptosis. This protein kinase can be activated by insulin, various growth factors, and survival factors, functioning through a wortmannin-dependent pathway involving PI3 kinase. Activation of Akt requires phospholipid binding and phosphorylation at two sites: phosphorylation at the catalytic domain Thr308 mediated by PDK1, and phosphorylation at the carboxyl terminal Ser473. The previously unknown PDK2 responsible for phosphorylating Akt at Ser473 has been identified as mTOR (mammalian target of rapamycin), which exists in a rapamycin-insensitive complex containing rictor and Sin1.

Androgen receptor (AR), a zinc finger transcription factor belonging to the nuclear receptor superfamily, is activated by phosphorylation and dimerization upon ligand binding. This promotes nuclear localization and binding of AR to androgen response elements in androgen target genes. Research studies have shown that AR plays a crucial role in several stages of male development and the progression of prostate cancer.

Adipogenesis is the process by which mesenchymal stem cells (MSCs) differentiate into mature adipocytes, categorized into white adipogenesis (white adipocytes) and brown adipogenesis (brown adipocytes).

AMP-activated protein kinase (AMPK) is highly conserved from yeast to plants and animals and plays a key role in the regulation of energy homeostasis。

Glutamate is the most abundant excitatory neurotransmitter in the central nervous system of vertebrates. Once released into the synaptic cleft, it depolarizes the postsynaptic membrane and activates downstream signaling pathways, thereby propagating excitatory signals. The initial depolarization is primarily mediated by α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors.

Actin is one of the most abundant proteins in eukaryotic cells and is a key component of the cytoskeleton, the internal framework of the cell. Its most remarkable characteristic is its dynamic nature—it can rapidly assemble and disassemble, thereby driving cell movement and changes in cell shape.
