Limits of using compound 48/80 and standard mast cell lines in tick saliva research

Synthesizes why compound 48/80 cannot provide a safe assay window in HMC1.2 and RBL-2H3 cell lines for screening tick salivary anti-inflammatory effects: only 48/80 is effective in both models, but is toxic at working concentrations, and the observed degranulation is mainly an artifact of permeabilization rather than genuine activation.

Reasoning Steps (3)

Only 48/80 induces degranulation in both cell modelsStep 1
No non-toxic window for 48/80 in HMC1.2 and RBL-2H3Step 2
β-hexosaminidase release is largely due to cell permeabilizationStep 3

Knowledge Gaps (1)

No safe positive control for degranulation in these assays
