Transforming Growth Factor beta (TGFβ) is a complex polypeptide that plays a vital role in cell differentiation, proliferation, and survival. It regulates various cellular functions, including immune response, tissue repair, and wound healing. However, when TGFβ is overexpressed or dysregulated, it can contribute to the development of many diseases, including cancer, fibrosis, and autoimmune disorders. As such, identifying antonyms for TGFβ could potentially help in developing targeted therapies for these conditions. Some possible antonyms include inhibitory agents that block TGFβ signaling or promote its degradation, or activators that enhance the expression of other growth factors that counteract the effects of TGFβ.
