      Type 2 inflammation is a pattern of immune response. Its physiological function is to defend the body against helminths, but a dysregulation of the type 2 inflammatory response has been implicated in the pathophysiology of several diseases.


      Molecular biology


      IL-25, IL-33, and TSLP are alarmins released from damaged epithelial cells. These cytokines mediate the activation of type 2 T helper cells (Th2 cells), type 2 innate lymphoid cells (ILC2 cells), and dendritic cells. Th2 cells and ILC2 cells secrete IL-4, IL-5 and IL-13.
      IL-4 further drives CD4+ T cell differentiation towards the Th2 subtype and induces isotype switching to IgE in B cells. IL-4 and IL-13 stimulate trafficking of eosinophils to the site of inflammation, while IL-5 promotes both eosinophil trafficking and production.


      Dysregulation in human disease


      Type 2 inflammation has been implicated in several chronic diseases:

      Asthma
      Atopic dermatitis
      Chronic sinusitis with nasal polyps
      Eosinophilic esophagitis
      Bullous pemphigoid
      Persons with one type 2 inflammatory disease are more likely to have other type 2 inflammatory diseases.


      Pharmacological targets


      Several medicines have been developed that target mediators of type 2 inflammation:

      IL-4-specific blockers:
      Altrakincept
      Pascolizumab
      IL-5-specific blockers:
      Benralizumab
      Mepolizumab
      Reslizumab
      IL-13-specific blockers:
      Lebrikizumab
      Tralokinumab
      Dual IL-4 and IL-13 blockers:
      Dupilumab
      IgE-blockers:
      Ligelizumab
      Omalizumab
