RESUMO
Cancer immunotherapy comprises different therapeutic strategies that exploit the use of distinct components of the immune system, with the common goal of specifically targeting and eradicating neoplastic cells. These varied approaches include the use of specific monoclonal antibodies, checkpoint inhibitors, cytokines, therapeutic cancer vaccines and cellular anticancer strategies such as activated dendritic cell (DC) vaccines, tumor-infiltrating lymphocytes (TILs) and, more recently, genetically engineered T cells. Each one of these approaches has demonstrated promise, but their generalized success has been hindered by the paucity of specific tumor targets resulting in suboptimal tumor responses and unpredictable toxicities. This review will concentrate on recent advances on the use of engineered T cells for adoptive cellular immunotherapy (ACI) in cancer.

Galectins are family of galactose-binding proteins known to play critical roles in inflammation and neoplastic progression. Galectins facilitate the growth and survival of neoplastic cells by regulating their cross-talk with the extracellular microenvironment and hampering anti-neoplastic immunity. Here, we review the role of galectins in the biology of hematological malignancies and their promise as potential therapeutic agents in these diseases.
