WebType 2 asthma is a widely prevalent type of persistent, uncontrolled asthma 26 and includes allergic asthma and eosinophilic asthma phenotypes, which have overlapping pathophysiological mechanisms. 8 It is well established that IL-4 and IL-13 are key drivers of cT2 such as atopic dermatitis, allergic rhinitis, nasal polyps, and eosinophilic esophagitis. … WebThe term “endotype” has been recently suggested to identify a subtype of the disease defined by pathophysiological mechanisms and treatment response. The most common approach for identifying asthma endotypes is centered on the immune response mediated by cells called T helper-2 (Th2) lymphocytes (Th2-low vs Th2-high).

In contrast, Th2-low endotype of asthma is characterized by neutrophilia, which is associated with a neutrophil extracellular trap formation and promotion of tissue injury, as well as an increased level of IL-17, which results in the propagation of proinﬂammatory cytokines [31]. Web9 Feb 2024 · However, it is unresolved whether this is indeed the case. Scepticism about the notion of a neutrophilic endotype is justified. Firstly, there is no accepted definition of neutrophilic asthma.
