LASN01
Based on 1 Customer Validation
LASN01 is a humanized antibody targeting IL-11R, with a Kd of 37 pM. LASN01 blocks the IL-11 signaling pathway via IL-11Rα, and inhibits the phosphorylation of STAT3 and ERK, as well as the expression of pro-inflammatory cytokines, hyaluronic acid, procollagen and fibrotic markers. LASN01 can be used in studies related to thyroid eye disease.

LASN01 (0.001-100 nM; 1 h) inhibits IL-11-induced activation of pSTAT3 and pERK in DLD-1 cells, with IC50 values of 0.4 nM and 0.1 nM, respectively[1].
LASN01 (1-10 µg/mL; 1 h) inhibits the phosphorylation of STAT3, ERK and AKT induced by IL-11 as well as by IL-11+IGF-1 in orbital fibroblasts derived from TED patients[1].
LASN01 (0.003-10 µg/mL; 97 h) inhibits IL-11-induced hyaluronic acid (HA) release in orbital fibroblasts derived from patients with TED, with an IC50 of 50 ng/mL[1].
LASN01 (3 µg/mL; 97 h) inhibits the release of proinflammatory cytokines (including IL-6 and CCL2) induced by IL-11+IGF-1 in orbital fibroblasts derived from patients with TED[1].
LASN01 (3 µg/mL; 97 h) inhibits the release of type I procollagen in orbital fibroblasts derived from patients with thyroid-associated ophthalmopathy (TED) induced by TGFβ[1].
LASN01 (1-10 µg/mL; 6-48 h) modulates IL-11-induced and IL-11+IGF-1-induced gene expression in orbital fibroblasts derived from patients with thyroid-associated ophthalmopathy (TED), and specifically inhibits pathways related to inflammation, cytokine signaling and fibrosis[1].
