Abstract

Taniguchi <i>et al</i> (Research Articles, 17 July 2020, p. 269) claim that the cytokine interleukin-33 induces accumulation of tumor-associated macrophages expressing the immunoglobulin E receptor FcεRI. Although these findings hold great therapeutic promise, we provide evidence that the anti-FcεRI antibody used in this study is not specific for FcεRI on macrophages, which raises concerns about the validity of some of the conclusions.
