Inducción de la expresión de citocinas por Mycobacterium tuberculosis en un modelo de rebanadas de tejido pulmonar por Carranza Torres, Irma Edith

“…All the results showed that M. bovis BCG (non-virulent) induced a higher cytokine expression than M. tuberculosis H37Rv (virulent) suggesting an inhibition of innate immune response by the virulent strain, as a possible mechanism to facilitate its survival in the tissue. The results of this work show that lung tissue slices model infected with M. tuberculosis may be a very useful tool to evaluate the innate immune response and other aspects during the early stages of mycobacterial infection.…”

Mecanismos de acción de bacitracina y el ácido 5,5’-ditiobis2-nitrobenzoico en la infección del virus de inmunodeficiencia humana tipo I por Flores Treviño, Samantha Maribel

“…Also, both Bacitracin and DTNB seem to depend on the tropism exhibited by HIV-1 strains to efficiently inhibit HIV-1 infection when exposed only to the virus itself. Furthermore, cell-based fusion assays were performed for these two compounds and as expected, both Bacitracin and DTNB showed inhibition in a dose-dependent manner when exposed to both type cells, which could easily suggest that both Bacitracin and DTNB seem to act highly on gp120 and/or gp41, and also on Tat, Rev, Nef and/or Gag-products. …”
