研究问题
Laminins are heterotrimeric glycoproteins assembled from five α chains (α1–α5), three β chains (β1–β3), and three γ chains (γ1–γ3).
方法
The search was limited to English-language records and included no date restriction.；We considered mechanistic, in vitro, ex vivo, animal, observational human, and interventional human studies when available.；For neurodegeneration, current evidence should be classified as association, mechanism, or intervention/rescue.；Laminin-111 has been shown to enhance wound healing in animal models, particularly in diabetes-associated impaired wound healing [103].
核心结论
Introduction Laminins are heterotrimeric glycoproteins assembled from five α chains (α1–α5), three β chains (β1–β3), and three γ chains (γ1–γ3).；The three-number laminin nomenclature identifies the α, β, and γ chains in that order; for example, laminin-111 contains α1, β1, and γ1, whereas laminin-332 contains α3, β3, and γ2.；The α, β, and γ chains contain distinct N-terminal and C-terminal domains that contribute to heterotrimer assembly, matrix polymerization, receptor binding, and proteolytic processing. ‖ 结论：For proteins and biomaterials, critical quality attributes, sterility, bioburden, stability, process qualification, and change control must be established before clinical testing.
