Characterization and Comparison of LAD2 and LADR Mast Cell Lines: Insights into Mastocytosis and HIV Infection
LAD2 and LADR cell lines are invaluable tools in mast cell research, offering insights into mastocytosis and immune responses. Derived from CD34+ cells, LAD2 cells have been extensively used for over 18 years, while LADR cells, a newer variant, exhibit enhanced characteristics such as larger size, increased granulation, and faster doubling time. Both cell lines release granular contents upon FceRI aggregation and can be infected with various strains of HIV. LADR cells, in particular, show greater expression of certain surface receptors and mRNA compared to LAD2 cells.
