CALR and neoplasm: We measured the effects of I‐PTT and S‐PTT on published, consensus ICD correlates calreticulin, adenosine triphosphate (ATP), and HMGB1 as a function of thermal dose.[48] In the study with N2A tumor cells, I‐PTT induced the higher surface expression of calreticulin compared to S‐PTT, with median fluorescence intensity (MFI) levels increasing from 814 to 5561 with I‐PTT, while S‐PTT generated MFIs of 654 and 3209 at thermal dose of 2.0 and 4.5, respectively (Figure 4a,b and Figure S7, Supporting Information), although this was not statistically significant.
