It is speculated that structural and secretory proteins of C. albicans have immunomodulatory effects in cancer. Objective: To evaluate the effects of C. albicans structural and secreted proteins on intratumoral CD4/CD8 ratio as well as the survival rate in BALB/c tumor model. Methods: Structural and secretory proteins from C. albicans were isolated and examined for their effects on tumor growth and survival of adenocarcinoma bearing mice. Results: The results indicated that in mice treated with C. albicans structural protein, the survival rate significantly decreased compared with the control groups. Also, mice treated with secretory proteins showed a decrease in survival rate but it was not statistically significant (p>0.05). Investigating the frequency of tumor infiltrated CD4+ and CD8+ T lymphocytes indicated that the percentages of tumor infiltrated CD4+ T lymphocytes in response to structural and secreted proteins were higher compared to the control groups. Conclusion: Our study suggests that C. albicans structural and secreted proteins modulate intratumor T lymphocyte infiltration.}, keywords = {candida albicans,Lymphocytes,Spontaneous Adenocarcinoma,Structural Proteins,Secreted Proteins}, url = {https://iji.sums.ac.ir/article_17051.html}, eprint = {https://iji.sums.ac.ir/article_17051_b02369f7b5b77a151aaf9a82f6e7f545.pdf} }
