EDUCATION SUMMARY

Dr Leticia Cedillo-Barrón is a Bacteriologist and Parasitologist, specialist in Virology and Immunology. She obtained a Master and PhD in Immunology doing research in Malaria and lecturing at the National School of Biological Sciences (ENCB-IPN). She then joined the team of Professor Michael Parkhouse at the Institute for Animal Health in Pirbrigh (UK) obtaining first a fellowship from the Wellcome foundation for two years. She then got her training in Virology and Molecular Biology with the exotic viruses such as FMDV and ASF. After, she was hired by the European Community at the same institution for 4 years, when she was involved in the evaluation of different targets of protective immunogens for the elaboration of potential recombinant vaccines. Currently she is working at CINVESTAV since the year 2000. Level II of the SNI (2014-)

  • Research articles published: 51

  • Chapters in books 4

  • Direction of Doctoral Thesis: 14.

  • Direction of Master Thesis: 20

  • Direction of Bachelor Thesis: 1

RESEARCH TOPICS

  • Dengue virus and its proteins involved in immunopathogenesis.

  • Innate immunity against Dengue, Zika and CHIKV viruses.

  • Recombinant vaccines against Dengue virus. Research and teaching experience

RESEARCH INTEREST

In our laboratory, we are interested in Characterization of the early events involved in innate immunity against Dengue virus.
Is well known that DENV can trigger apoptosis in host cells in vitro and in vivo. We are interested to elucidate the viral proteins and the mechanisms by which DENV trigger apoptosis. The elucidation of this phenomena may be critical to understand dengue pathogenesis in the early times of infection
Additionally, we are studying the immune responses in animal models and also in patients from Dengue outbreaks in different regions of Mexico.
