2004 - Fellow of John Simon Guggenheim Memorial Foundation
His primary areas of study are Immunology, Toxoplasma gondii, Immune system, Trypanosoma cruzi and Virology. His research investigates the link between Immunology and topics such as Interleukin 12 that cross with problems in Interleukin. The various areas that he examines in his Toxoplasma gondii study include Tumor necrosis factor alpha, CD8, Molecular biology, Spleen and In vivo.
His research in Immune system intersects with topics in Antibody and Microbiology. He interconnects Chemokine, Chagas disease, Interleukin 4, Proinflammatory cytokine and Parasitemia in the investigation of issues within Trypanosoma cruzi. His Virology research integrates issues from Leishmaniasis and DNA.
His main research concerns Immunology, Virology, Immune system, Trypanosoma cruzi and Antigen. Toxoplasma gondii, Cytokine, CD8, Innate immune system and Antibody are the subjects of his Immunology studies. His research integrates issues of Epitope, Immunization and Recombinant DNA in his study of Virology.
His research in Immune system focuses on subjects like Cell biology, which are connected to Receptor. His Trypanosoma cruzi research also works with subjects such as
His primary areas of investigation include Immunology, Virology, Antigen, Immune system and Cytotoxic T cell. His research on Virology often connects related areas such as Leishmania infantum. His Antigen study combines topics from a wide range of disciplines, such as Visceral leishmaniasis, Gastroenterology, Molecular biology, Internal medicine and Parasitemia.
The Immune system study combines topics in areas such as Trypanosoma cruzi, Antibody and Plasmodium falciparum. His biological study spans a wide range of topics, including Transcriptome, Microbiology, Chagas disease, Epitope and Virulence. His research on Cytotoxic T cell also deals with topics like
Ricardo T. Gazzinelli spends much of his time researching Immunology, Virology, CD8, Granzyme and Innate immune system. His Immune system and CCR4 investigations are all subjects of Immunology research. His study in Immune system is interdisciplinary in nature, drawing from both Epitope, Leishmania infantum, Leishmania and Cutaneous leishmaniasis.
His Virology research incorporates themes from Microbiology, Plasmodium vivax, Naive B cell, Antibody and Virulence. His work carried out in the field of CD8 brings together such families of science as Spleen, Receptor, Lung injury and Plasmodium berghei. His Innate immune system research is multidisciplinary, relying on both Plasmodium falciparum, Malaria, Hemozoin and Immunity.

In the absence of endogenous IL-10, mice acutely infected with Toxoplasma gondii succumb to a lethal immune response dependent on CD4+ T cells and accompanied by overproduction of IL-12, IFN-gamma and TNF-alpha.
