Importance of the field: The Notch signaling pathway regulates a variety of processes and has been linked to diverse effects. Aberrant Notch function is important in several disorders. Pre-clinical studies have suggested that inhibition of Notch is an attractive approach to treat hematologic and solid malignancies. Many patients with refractory autoimmune diseases respond poorly to therapy and have significant morbidity and the treatment is highly toxic, so more effective therapies for autoimmune diseases are being examined.
Areas covered in this review: The role of the Notch pathway and therapeutic strategies targeting it in many illnesses, especially autoimmune diseases.
What the reader will gain: The Notch pathway has unique and attractive advantages for targeting. Targeting it has already been trialed in many experiments, which may show better efficacy and fewer side effects compared with classical drugs for the treatment. Targeting Notch might provide etiological rather than symptomatic treatment.
Take home message: Various methods targeting the Notch pathway have been under investigation. Rational targeting of the Notch signaling pathway in cancer and some autoimmune diseases has proven to be successful. Classical drugs for the treatment of autoimmune diseases are inefficient and toxic to some extent, and targeting the Notch pathway is a promising therapeutic concept. However, there are still many questions about targeting Notch in autoimmune diseases, and further investigation will be needed.
