Final Answer:
The drug used for blocking IL31 is C) Dupilumab. Therefore the correct option is C) Dupilumab.
Step-by-step explanation:
The drug used for blocking IL-31 is Dupilumab (option C). Interleukin-31 (IL-31) is a cytokine associated with inflammatory and pruritic (itching) responses, particularly in conditions like atopic dermatitis. Dupilumab is a monoclonal antibody that specifically targets and inhibits the action of IL-31, providing relief from symptoms associated with inflammatory skin disorders.
Dupilumab's mechanism involves binding to the IL-31 receptor and preventing IL-31 from exerting its inflammatory effects. By blocking IL-31, Dupilumab helps alleviate itching and reduce inflammation, making it an effective treatment for conditions where IL-31 plays a significant role, such as atopic dermatitis. This targeted approach minimizes side effects associated with broader immunosuppression, enhancing the drug's therapeutic profile.
In clinical settings, Dupilumab has shown efficacy in improving the quality of life for patients with atopic dermatitis, leading to its approval for use in various countries. The specificity of Dupilumab for IL-31 underlines the importance of targeted therapies in managing inflammatory and immune-related conditions, providing a more favorable risk-benefit profile compared to non-specific immunosuppressive agents.Therefore the correct option is C) Dupilumab.
