stromaltargeting

Stromaltargeting refers to a therapeutic strategy focused on inhibiting or disrupting the function of stromal cells within a tumor microenvironment. The stroma is a complex network of non-cancerous cells, including fibroblasts, immune cells, endothelial cells, and extracellular matrix components, that surrounds and supports tumor growth. While cancer cells are the primary targets of many anti-cancer therapies, the tumor stroma plays a crucial role in tumor progression, metastasis, and resistance to treatment.

Stromal cells can promote tumor growth by secreting growth factors and cytokines that stimulate cancer cell proliferation. They also contribute to angiogenesis, the formation of new blood vessels that supply the tumor with oxygen and nutrients. Furthermore, the extracellular matrix produced by stromal cells can create a physical barrier that hinders the penetration of chemotherapy drugs and immune cells. In some cases, stromal cells can also suppress the anti-tumor immune response.

Stromaltargeting aims to neutralize these pro-tumorigenic activities of the stroma. This can be achieved through various approaches, such as targeting cancer-associated fibroblasts (CAFs) which are a major component of the tumor stroma, or by modulating the extracellular matrix. Another strategy involves targeting the immune cells within the stroma to enhance the anti-tumor immune response. By disrupting the supportive role of the stroma, stromaltargeting therapies aim to make tumors more susceptible to conventional treatments and to prevent metastasis. Research in this area is ongoing, with the goal of developing novel and more effective cancer treatments.
