LM22B 10 BiologicalActivity
| Description | LM22B-10 is an activator of TrkB/TrkC neurotrophin receptor, and can induce TrkB, TrkC, AKT and ERK activation in vitro and in vivo. |

| In Vitro | LM22B-10 exhibits maximum neurotrophic survival activity levels that are higher than those maximally achieved with BDNF (53 ± 7.2% above BDNF at 0.7 nM) and NT-3 (91 ± 8.6% above NT-3 at 0.7 nM) with an EC50 value of 200-300 nM. LM22B-10 (1000 nM) induces neurites of significantly larger average lengths, up to -40 μM. LM22B-10 (250-2000 nM) binds to TrkB-Fc and TrkC-Fc in a dose-dependent manner. LM22B-10 inhibits binding of BDNF to TrkB-expressing cells and NT-3 to TrkC-expressing cells. LM22B-10 promotes cell survival and functions preferentially through TrkB and TrkC. LM22B-10, but not BDNF or NT-3, promotes neurite outgrowth in an inhibitory environment. LM22B-10 induces patterns of Trk and downstream signaling activation that are distinct from those of BDNF and NT-3. LM22B-10 also induces TrkB, TrkC, AKT and ERK activation in hippocampal neurons in culture[1]. |
| In Vivo | LM22B-10 (0.5 mg/kg) activates TrkB, TrkC, AKT and ERK in C57BL/6J mice. LM22B-10 (50 mg/kg, i,p,) shows increased phosphorylation at TrkBY817 and TrkCY820. LM22B-10 activates synaptic TrkB and TrkC and increases pre- and post-synaptic proteins and spine density in aged mice[1]. |
| Cell Assay | Mouse NIH-3T3 cells, mouse NIH-3T3 cells expressing TrkA (NIH-3T3-TrkA) or p75NTR (NIH-3T3-p75NTR), and NIH-3T3 cells expressing TrkB (NIH-3T3-TrkB) or TrkC (NIH-3T3-TrkC) are propagated in DMEM supplemented with 10% FBS and 200-400 μg/mL Geneticin (for Trk-expressing cells) or 400 μg/mL hygromycin (for p75NTR-expressing cells). Cells are seeded into 24-well plates (30,000 cells/well) and cultured in medium consisting of 50% PBS and 50% DMEM without supplements. Following exposure to growth factors (0.7 nM) or 1000 nM LM22B-10 for 72-96 h, cells are suspended in 50 μL lysis buffer, transferred to opaque 96-well culture plates and survival is measured using the ViaLight Assay. |
