Dr. Trujillo’s contributions to science have opened doors to the profound study of neurological diseases. He has worked in clinical and basic neuroscience research for over 25 years and has spent the last 10 years in translation research for brain regeneration technology. Dr. Trujillo has been on various scientific editorial boards and has published over 60 scientific manuscripts and reviews, and more than 50 conference abstracts and book chapters.

His most famous research includes antiviral immune responses in the nervous system, opportunistic AIDS infections, such as neurocysticercosis, and the molecular basis of neurotropism of HIV-1. He has also conducted cancer research and published articles on photodynamic therapy.

Dr. Trujillo’s paper on molecular mimicry between the human immunodeficiency virus type 1 gp120 V3 loop and human brain proteins was recognized as the scientific article of the year by Harvard University and by the American Society of Microbiology. He was the first medical scientist to identify a non-infectious sugar receptor MR for HIV-1 pathogenesis, an ingenious insight for viral vaccines, which was published in the Proceedings of the National Academy of Sciences.

Dr. Trujillo has been an intramural investigator at the National Institute of Neurological Disorders and Stroke at the NIH. He was also the Director of Latin American Research in Virology and Neurosciences and Head of the Laboratory of Neurovirology at the Institute of Human Virology, USA.

The Mannose Receptor of Macrophages: The non-infectious pathway of HIV

Jileta Alida , Trujillo JR.
Rev Mex Neuroci. 2009; 10 (1):44-48.

Mannose Receptor
The glycoprotein spikes (yellow) on the surface of HIV are covered with sugars called mannose. If one of these sugars binds to a mannose receptor (red) on the surface of a macrophage, the immune cell will ingest the virus via phagocytosis. HIV will then be destroyed, and the cell will not be infected.

Neurocysticercosis and HIV protection Co-infection of the central nervous system by opportunistic pathogens represents a common cause of consultation. Neurocysticercosis illustrates a parallel epidemic to that of AIDS. Epidemiological phenomenon suggests mutual protection between both infections.
