The protein encoded by IFNLR1 is Interferon lambda receptor 1, also known as IL28Rα. It forms a heterodimer with IL10Rβ to act as the functional receptor for type III interferons (IFN-λs). Ligand binding triggers JAK-STAT pathway activation, driving transcription of antiviral and immune-regulatory genes, critical for innate defense against viral infections.
Dysregulation of IFNLR1 signaling links to chronic HCV infection, COVID-19, and autoimmune disorders like SLE. Drug development includes IFN-λ agonists for viral diseases and antagonists for excessive inflammation, with several candidates in preclinical or early clinical stages, showing potential in modulating immune responses.

IHC image of CSB-PA816871ESR1HU diluted at 1:200 and staining in paraffin-embedded human small intestine tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB.

Immunofluorescence staining of MCF-7 cells with CSB-PA816871ESR1HU at 1:100, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
