Targeting Cancer-Associated Fibroblasts: Eliminate or Reprogram?

Area of Science:

• Oncology
• Immunology
• Cell Biology

Background:

• Cancer-associated fibroblasts (CAFs) are integral to the tumor microenvironment (TME).
• CAFs significantly impact tumor progression, metastasis, and resistance to therapies.
• Their dual role in promoting or suppressing tumors necessitates targeted strategies.

Purpose of the Study:

• To review the origins, diversity, and functions of CAFs in cancer.
• To explore current therapeutic strategies targeting CAFs.
• To discuss the challenges and future directions in CAF-targeted cancer therapy.

Main Methods:

• Literature review of preclinical and clinical studies on CAFs.
• Analysis of CAF heterogeneity and plasticity.
• Evaluation of therapeutic approaches including CAF elimination and reprogramming.

Main Results:

• CAFs exhibit significant heterogeneity and plasticity, complicating therapeutic targeting.
• Strategies to eliminate tumor-promoting CAFs show potential in preclinical models.
• Reprogramming CAFs in combination with immunotherapy is an emerging therapeutic avenue.

Conclusions:

• Targeting CAFs presents a promising strategy for cancer treatment.
• Understanding CAF plasticity and heterogeneity is critical for developing effective therapies.
• Future research should focus on developing methods to selectively target tumor-promoting CAFs while sparing tumor-suppressive ones.
