Photodynamic therapy Light stimulates a photosensitizer to release toxic singlet oxygen which destroys targeted cancer cells . See paper

mannose receptor.jpg

Model of noninfectious HIV-1 entry into antigen presenting cells. The mannose-rich carbohydrates of gp120 initiate a noninfectious phagocytic pathway. This pathway links microbial antigen recognition by mannose receptors with presentation by CD1b, for the induction of cell-mediated immunity.  See paper

Neurocysticercosis & HIV .jpg

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. See paper

Virology cover.jpg

Featured cover article in Virology Shared antigenic epitopes on the V3 loop of HIV-1 gp120 and proteins on activated human T cells. Shown for the first time that our CD4 T-cells are killed by the immune system due to molecular mimicry. See paper

Shared antigenic epitopes on the V3 loop of HIV-1 gp120 and proteins on activated human T cells. Trujillo JR, Rogers RA, Brain JD. Virology. 1998;246(1):53-62. doi:10.1006/viro.1998.9185

Molecular Mimicry and HIV.jpg

Molecular mimicry Immunologically cross-reactive proteins in the human brain that resemble the V3 loop of HIV GP120 have been identified. An immune response to the V3 loop that generates cross-reactive antibodies to cellular proteins may be an autoimmune mechanism by which HIV can damage the central nervous system. See paper


Neurologic manifestations of AIDS: a comparative study of two populations from Mexico and the United States. Trujillo JR, Garcìa-Ramos G, Novak IS, Rivera VM, Huerta E, Essex M. J Acquir Immune Defic Syndr Hum Retrovirol. 1995;8(1):23-29.

Neuropathogenesis of HIV-1 Infection Microglia infection by HIV has been pathologically associated with “HIV encephalitis”. Neurons and astrocytes infection by HIV has been associated with “HIV encephalopathy”. The HIV T tropic phenotype is responsible for astrocyte/neuron infection in absence of CD4 receptor and some cases the presence of CXCR4. See paper
