The TSLP gene encodes a hemopoietic cytokine proposed to signal through a heterodimeric receptor complex composed of the thymic stromal lymphopoietin receptor and the IL-7R alpha chain. This mainly impacts myeloid cells and induces the release of T cell-attracting chemokines from monocytes and enhances the maturation of CD11c(+) dendritic cells. The protein promotes T helper type 2 (TH2) cell responses that are associated with immunity in various inflammatory diseases, including asthma, chronic obstructive pulmonary disease and allergic inflammation. The protein is therefore considered a potential therapeutic target for the treatment of these diseases. Alternative splicing of this gene results in multiple transcript variants.
