一、前言肿瘤细胞为什么会不断地繁殖?细胞繁殖控制的机转是怎样的?肿瘤细胞在体内怎样从一处转到另一处?细胞主动移动的机理是怎样的?近年来发现这些问题都和细胞膜及其相连的微丝、微管有关。当淋巴细胞膜的表面免疫球旦白与其相应配体结合时,当巨噬细胞进行吞食作用时,细胞膜出现什么样的变化?这些都是和免疫机制有密切关系的问题。本文对这些问题近年的进展加以叙
I. Introduction Why do tumor cells continue to multiply? What are the mechanisms of cell proliferation control? How do tumor cells move from one place to another in the body? What is the mechanism of active cell movement? These problems have been discovered in recent years. It is related to the cell membrane and its associated microfilaments and microtubules. When the surface of the lymphocyte membrane immunoglobulin binds to its corresponding ligand, what happens to the cell membrane when the macrophages ingest food? These are all problems that are closely related to the immune mechanism. This article describes the progress of these issues in recent years.
