Defective generalized extracellular matrix in the neoplasm bearing host: decreased inflammation, immunity and
Abstract:
Neoplasms have extensive qualitative and quantitative changes in their extracellular matrix. Lytic factors from neoplasms breakdown extracellular matrix of the areas adjacent to the neoplasms and fibroblasts in these areas produce increased extracellular matrix. Some of the extracellular matrix fractions are normally present in serum. Multiple fractions derived from extracellular matrix are present in the serum of tumor patients. Tumor patients often have decreased early cellular inflammation and immunity. These reactions depend on a normal extracellular matrix. A number of known facts about the tumor bearing host can be explained by the concept that the host's generalized extracellular matrix is altered by circulating fractions of extracellular matrix. These could be qualitative or quantitative defects as well as an abundance of depolymerized fractions. The beneficial effects of cytokines, streptococcal infections and pyridoxine deficiency on tumors can be explained by this concept.
