Resumen
La depresión es uno de los trastornos mentales que presenta una gran prevalencia, ya que afecta a cerca del 16% de la población general. Actualmente, la mayoría de los estudios coinciden en que este trastorno se produce por una interacción entre algún tipo de predisponente genético y diversos factores ambientales. Es por ello que la investigación de los mecanismos que median dicha interacción cobra vital importancia para conseguir avanzar en la comprensión de los mecanismos etiopatogénicos que originan el trastorno depresivo, y por ende para lograr herramientas más eficaces para su tratamiento y prevención. Durante las últimas décadas gran parte de los estudios sobre las bases neurobiológicas de la depresión evolucionaron a partir de dos grandes hipótesis, la teoría monoaminérgica y la teoría neurotrófica. El objeto del presente artículo es hacer una revisión de los hallazgos científicos que avalan ambas teorías.

Palabras clave
depresión, monoaminas, receptores, plasticidad neuronal, factores neurotróficos

Abstract
Mood disorders are among the most prevalent forms of mental illness. Thus, up to 16% of the population is affected by depression. Actually, all the scientific studies agree that depression is mainly produced by an interaction between genetic and environmental causes. In this context, the study of this interaction is a key point in order to better understand the pathophysiology of depression and to improve its treatment and prevention.
During the last years, the efforts to try to understand the neurobiological basis of depression have mainly focus on two hypothesis: the monoamine hypothesis and the neurotrophic hypothesis. The aim of the present article is to review the scientific evidences that support both hypothesis.

Key words
depression, monoamines, receptors, neural plasticity, neurotrophic factors
