RESUMO
Immunotherapy is one of the most innovative treatments in the current field of oncology and consists of stimulating the immune system to eliminate tumoral cells. Monoclonal antibodies (mAbs) are glycoproteins secreted by B-cells capable of recognizing and neutralizing foreign organisms or antigens. Structurally, they are composed of two heavy and two light chains. The generation of therapeutic mAbs is one of the most developed and fastest-growing areas of the biotechnological and pharmaceutical industries and is an important adjunct to cancer therapy. Several antibodies have been approved for human administration and can be mouse-derived, chimeric, humanized, or fully human. mAbs main mechanism of action includes the lysis of the tumoral cells through inducing apoptosis, phagocytosis, complement activation, or signaling inhibition.

La generación de mAbs terapéuticos es una de las áreas de mayor crecimiento en la industria biotecnológica y farmacéutica y representa un complemento importante en la terapia del cáncer. Existen diversos mAbs que han sido aprobados para su administración en humanos, y pueden ser derivados de ratón, quiméricos, humanizados o completamente humanos. Los mecanismos de acción consisten principalmente en la lisis de las células tumorales a través de la inducción de la apoptosis, fagocitosis, activación del complemento o inhibición de la señalización celular.

RESUMO
SARS-CoV-2 was first detected in the city of Wuhan, Hubei Province, China. In this report, we describe the complete genome sequence of the first imported SARS-CoV-2, detected in a Mexican patient who had traveled to Bergamo, Italy. Phylogenetic analysis showed that this isolate belongs to subclade A2a (lineage G) and is closely related to isolates from Finland, Germany and Brazil, all of which were from patients with a history of travel to Italy. This is the first report of the complete genome sequence of this virus in Mexico.
