What are the potential side effects or risks associated with (Ile76)-TNF-α (70-80) in therapeutic use?

While (Ile76)-TNF-α (70-80) itself is primarily a research tool at this stage, understanding the potential side effects or risks associated with modulating this peptide's activity is crucial when considering its therapeutic applications. Generally, due to its origin from TNF-α, which is a significant player in inflammatory and immune responses, any therapeutic use involving (Ile76)-TNF-α (70-80) or related agents would need to carefully balance enhancing beneficial immune responses and minimizing adverse effects.

One potential concern with utilizing (Ile76)-TNF-α (70-80) therapeutically could stem from its role in altering cytokine activity and immune system dynamics. Any intervention that modulates key immune checkpoints can lead to unintended consequences, such as increased susceptibility to infections or immune dysregulation. For instance, while suppression of TNF-α activity might be beneficial in reducing chronic inflammation in disorders like rheumatoid arthritis, it could also compromise the body’s ability to respond effectively to infectious pathogens. This compromises immune vigilance and might lead to a higher incidence of infections, including bacterial, viral, or fungal diseases.

Another potential side effect related to manipulating (Ile76)-TNF-α (70-80) activity arises from its influence on other cytokines and chemokines, which could result in a disruption of normal immune homeostasis.
