These molecules interact with specific receptors, particularly the Receptor for AGEs (RAGE), triggering intracellular signaling cascades that promote oxidative stress through the generation of Reactive Oxygen Species (ROS) and activation of inflammatory pathways. A critical pathological mechanism involves the formation of neoantigens, modified self-proteins that elicit immune responses. Structural alterations caused by AGEs expose new epitopes or modify existing ones, making them targets for autoreactive T cells and autoantibodies. This mechanism is implicated in autoimmune skin diseases such as vitiligo and bullous pemphigoid. Oxidative stress plays a central role in these diseases, exacerbated by AGEs through the generation of ROS and depletion of antioxidants, leading to melanocyte destruction in vitiligo and tissue damage in bullous pemphigoid. In addition, hypoxia enhances ROS production, mitochondria, and other cellular systems contributing to oxidative stress. Emerging evidence suggests that hypoxia can be mitigated by oxygen nanobubbles. Targeting AGE formation and oxidative stress presents a promising approach for the management of autoimmune skin disorders in DM1. Therapeutic strategies targeting AGE formation, oxidative stress, and immune dysregulation show promise for managing autoimmune skin disorders in Type 1 Diabetes Mellitus (T1DM). AGE inhibitors, such as aminoguanidine and pyridoxamine, reduce non-enzymatic protein glycation, limiting AGE accumulation and inflammatory signaling. Antioxidants, including polyphenols, vitamins C and E, N-acetylcysteine, selenium, and hydrogen-rich water, help neutralize Reactive Oxygen Species (ROS), restoring oxidative balance. Combining AGE inhibitors and antioxidants may provide synergistic benefits by reducing oxidative stress and protein immunogenicity. Additionally, immune modulation therapies, such as Treg therapy and cytokine inhibitors, aim to restore immune tolerance and prevent autoimmune activation. Anti-TNF-α and IL-6 inhibitors offer targeted inflammation suppression, while RAGE antagonists mitigate AGE-induced immune dysregulation.

It is one of the most challenging cancers to manage and constitutes a significant proportion of cancer-related fatalities. The rising incidence of breast cancer necessitates the pursuit of more effective treatments. Due to the association of most chemotherapeutic medications with drug resistance, cancer recurrence, and adverse effects, researchers are exploring more effective alternatives, such as natural chemicals for the treatment and prevention of breast cancer. Chemoprevention using chemicals derived from plants has become a viable and accessible method for managing and controlling cancer. Among the numerous phytochemicals exhibiting an extensive range of biochemical and pharmacologic properties, gingerols have been documented to be efficacious in inhibiting the transformation, hyperproliferation, and inflammatory mechanisms that commence and foster carcinogenesis, along with the subsequent stages of carcinogenesis, angiogenesis, and metastasis. The chemotherapeutic potential of gingerol has been shown in several in vitro and in vivo studies. Clinical research has also documented the effectiveness of gingerol in cancer management.
