Titanium Ions Promote Exogenous Calcium-Dependent Calcium Influx in Activated Jurkat T Cells: A Possible Mechanism to Explain Its Immunostimulatory Properties

Figure 4

Fluorescence imaging and [Ca²⁺]i analysis of unactivated T cells exposed to Ti(IV) ions. Ti(IV) has non-significant effect on calcium mobilization in unactivated T cells. Data are representative images from three separate experiments. (c) Fluorescent images captured by laser scanning microscopy show the unactivated cells exposed to different concentrations of Ti(IV) ions in the presence of extracellular Ca²⁺.
