Mechanism & Research Applications
Tofacitinib competitively inhibits JAK1 and JAK3 (and to a lesser extent JAK2), blocking STAT activation and interrupting cytokine-mediated signaling pathways. It’s widely used in lab settings for:
-
Immune signaling and cytokine modulation studies
-
Autoimmune inflammation and disease models
-
Comparative testing with other JAK inhibitors
-
Pharmacokinetic/pharmacodynamic profiling
-
Cell signaling and transcription regulation research
Side Effects (Research Model Observations)
Preclinical and lab studies have reported potential side effects including:
-
Decreased white blood cells (lymphopenia/neutropenia)
-
Elevated liver enzyme levels
-
Increased risk of infection markers and immunosuppression
-
Altered lipid metabolism and blood pressure changes
