Abstract
Currently, IgG is the only class of antibodies employed for cancer therapy. However, harnessing of the unique biological properties of a different class, IgE, could engender potent effector cell activation and unleash previously-untapped immune mechanisms against cancer. IgE antibodies are best known for pathogenic roles in allergic diseases and for protective effector functions against parasitic infestation, often mediated by IgE Fc receptor-expressing macrophages. Notably, IgE feature very high affinity for cognate Fc receptors expressed by tumor-associated macrophages (TAMs). Here we review pre-clinical studies that point towards control of cancer growth by tumor antigen-specific IgE that recruit and re-educate TAMs towards activated profiles. Further, we discuss the clinical development harnessing the anti-tumor potential of recombinant IgE antibodies in cancer patients.
