Glycans participate in many key biological processes including cell adhesion, molecular trafficking and clearance, receptor activation, signal transduction, and endocytosis. 多糖参与了许多关键的生物学过程，其中包括细胞粘附，分子运输，分子降解，受体活化，信号传导和细胞内吞作用。
So what should be emphasized is to look for primary photo-acceptors, study their interaction with lasers and the following process of signal transduction and amplification. 并指出探讨低强度激光生物效应机理，应着重于寻找并研究初始光受体与激光的相互作用，以及随后的信号传导与放大过程。
