Heat Shock Proteins exosomal localization and levels in non-tumoral and tumoral thyroid tissues

Exosomes (EXs) secreted from cells to the extracellular environment play an important role in intercellular communication in normality and pathology. In particular, EXs contribute to cancer progression through the modulation of tumor microenvironment. Heat Shock Proteins (Hsps) are implicated in the development of carcinogenic process because they interact with many metabolic and biomolecular mechanisms of cancer cells [1]. Different studies shown that they can be released by tumors cells and that the mechanism of release is mediated by EXs pathway. In this study we performed an immunomorphological and biomolecular analysis to investigate Hsp27, Hsp60, Hsp70, Hsp90 levels expression profile…
