Efficacy of adoptive therapy with tumor-infiltrating lymphocytes and recombinant interleukin-2 in advanced cutaneous melanoma: a systematic review and meta-analysis.

Adoptive cell therapy (ACT) using autologous tumor-infiltrating lymphocytes (TIL) has been tested in advanced melanoma patients at various centers. We conducted a systematic review and meta-analysis to assess its efficacy on previously treated advanced metastatic cutaneous melanoma. The PubMed electronic database was searched from inception to 17 December 2018 to identify studies administering TIL-ACT and recombinant interleukin-2 (IL-2) following non-myeloablative chemotherapy in previously treated metastatic melanoma patients.

Alteration of the metaphase checkpoint by B chromosomes.

The B chromosome polymorphism in Spanish populations of the grasshopper, Eyprepocnemis plorans (Charpentier) is ancient and widespread. Meiocytes containing B chromosomes were analyzed in our laboratory using the 3F3/2 monoclonal antibody, which binds to a kinetochore phosphoepitope whose degree of phosphorylation is sensitive to tension applied to the kinetochore. Further, the tension created by the spindle at metaphase controls a checkpoint (the metaphase checkpoint) that allows the cell to begin anaphase when all chromosomes are aligned at the metaphase plate.
