IC 100
IC 100 is a humanized IgG4κ monoclonal antibody targeting apoptosis-associated speck-like protein (ASC) with blood-brain barrier permeability. IC 100 specifically inhibits ASC after being endocytosed via its Fc segment, blocks ASC polymerization and inflammasome activation, suppresses IL-1β release, forms complexes with ASC and TRIM21, and evades TRIM21-mediated proteasomal degradation. IC 100 alleviates symptoms associated with autoimmune encephalomyelitis, reduces immune cell infiltration and microglial activation in the mouse EAE model. IC 100 is suitable for research on neuroinflammatory and inflammasome-related diseases such as multiple sclerosis. Isotype comparison: HY-P99003.

IC 100 (0.001-1 μg/mL) dose-dependently inhibits IL-1β release in LPS/ATP-stimulated whole human blood, with significant inhibition observed at 1.0 and 0.1 μg/mL[2].
IC 100 (1 μg/mL) is rapidly internalized into iBMDM, remains detectable intracellularly for at least 2 hours, and is partially recycled and secreted back into the extracellular medium[2].
IC 100 (5 μg/mL) can bind to intracellular ASC and TRIM21 in THP-1 cells and iBMDM, directly interact with purified TRIM21 in a cell-free system, evade degradation through the TRIM21-mediated ADIN pathway, and remain detectable in A549 WT and TRIM21 KO cells for at least 3 days after cellular uptake[2].
IC 100 (3 μM; 1 hour pre-incubation prior to ASC PYD filament formation; 1 hour incubation with pre-formed filaments for immunogold labeling) specifically binds to ASC PYD filaments and alters their architecture, without inhibiting TEV protease activity or binding to non-ASC control filaments[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
IC 100 (100 μg per animal; i.v.; single dose) exhibits broad tissue distribution in healthy mice, crossing the blood-brain barrier to penetrate brain and spinal cord parenchyma, with significant accumulation in multiple peripheral tissues (excluding thyroid and pancreas) at 48 hours post-administration[2].

Animal Model:C57BL/6 (2-month-old female; experimental autoimmune encephalomyelitis induced via intraperitoneal pertussis toxin injection on day 0, subcutaneous myelin oligodendrocyte glycoprotein peptide 35-55 injection on day 1, and second intraperitoneal pertussis toxin injection on day 2)[1]
-
Dosage:10 mg/kg; 30 mg/kg; 45 mg/kg
-
Administration:i.p.; every 4 days; 27 days
-
Result:Significantly reduced daily clinical EAE scores throughout the experiment at 30 mg/kg and 45 mg/kg, with overall disease curves significantly different from vehicle controls.
Reduced average peak clinical score, cut cumulative disease index by half, significantly decreased spinal cord-infiltrating CD4+ T cells and CD8+ T cells, significantly reduced total spinal cord microglia (CD45lowCD11b+ population) and MHCII+ activated microglia, and reduced spinal cord infiltration of CD11b+ MHCII+ activated myeloid cells at 30 mg/kg.
Reduced average peak clinical score and decreased cumulative disease index.
Penetrated the brain, spinal cord, liver, and spleen at all tested doses, with maximal levels in the brain and spinal cord observed at 30 mg/kg and 45 mg/kg.

Dosage:100 μg per animal
-
Administration:i.v.; single dose
-
Result:Showed broad tissue distribution, including penetration into the central nervous system (brain and spinal cord parenchyma).
Detected distribution in brain, spinal cord, heart, lungs, kidneys, liver, eyes, thyroid, stomach, pancreas, small intestine, large intestine, bladder, and ovaries at 48 hours post-injection.
Demonstrated statistically significant accumulation compared to untreated controls in brain, spinal cord, heart, lungs, kidneys, liver, eyes, stomach, small intestine, large intestine, bladder, and ovaries at 48 hours post-injection.
