Ustekinumab is a monoclonal antibody that targets interleukin-12 (IL-12) and interleukin-23 (IL-23), which are cytokines involved in inflammatory processes. It is primarily used in the treatment of autoimmune conditions such as psoriasis, psoriatic arthritis, and Crohn's disease. Ustekinumab is produced using recombinant DNA technology in mammalian cell lines, which allows for the generation of a highly specific and effective therapeutic agent. The drug functions by inhibiting the signaling pathways of IL-12 and IL-23, thereby reducing inflammation and modulating the immune response. Ustekinumab is administered via subcutaneous injection, and its dosing regimen typically involves an initial loading dose followed by maintenance doses at specified intervals. Common side effects may include injection site reactions, increased risk of infections, and potential allergic reactions. As with any biologic therapy, careful monitoring is essential to manage any adverse effects and to assess the drug's efficacy in individual patients.

Psoriasis is a chronic inflammatory skin disorder that affects approximately 2-3% of the world’s population. The most common form of the
disease is plaque psoriasis, which is a result of dysregulated cell growth.
Conventional treatment options for psoriasis include topical corticosteroids, phototherapy, and systemic drugs (oral retinoids, cyclosporine, and
MTX), but all of these therapies have limitations. 
Ustekinumab
is the latest biologic to be approved for the treatment of plaque psoriasis.
It is a human IgG1k monoclonal antibody that binds with high affinity and specificity to the p40 protein subunit used by both the interleukin-12
(IL-12) and interleukin-23 (IL-23) cytokines. IL-12 and IL-23 are naturally
occurring cytokines that are involved in inflammatory and immune
responses, such as NK cell activation and CD4+ T-cell differentiation
and activation. In in vitro models, ustekinumab is shown to disrupt IL12- and IL-23-mediated signaling and cytokine cascades by disrupting the
interaction of these cytokines with a shared cell-surface receptor chain,
IL-12?1. Ustekinumab is indicated for the treatment of adult patients (18
years or older) with moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy.
Adverse events associated with the use of ustekinumab included nasopharyngitis, upper respiratory tract infection, headache, fatigue, and diarrhea.
