28 Março 2023, 14:00 • Elsa Anes
Macrophage evasion strategies of pathogens
“Why phagocytosis needs not be a degrading experience for Mycobacterium tuberculosis?”
Second part: Tuberculosis
1.Tuberculosis: an old disease & overview of the infection
2. The Innate Phase: Tuberculosis & the art of macrophage manipulation. Phagosome maturation blockade by M. tuberculosis. The innate granuloma
3. The Latent Phase: adaptive granuloma & the art to survive to a robust immune response
4. Primo-infection Vs reactivation: The caveating granuloma & The art to induce strong inflammation
5. Control through programmed cell death and inflammation:Inflammasome activation by Koch’s bacilli
6. Concluding remarks: implications for therapeutic approaches

Módulo 2 Microbiologia Humana:Estratégias invasivas de enteropatogenos
14 Março 2023, 14:00 • Elsa Anes
Invasive strategies of enteropathogens: invading the epithelia
- Invading epithelial cells: Listeria, Yersinia, Shigella and Salmonella
- Intracellular pathogens: internalization step in epithelia an invasive process
- The actin Cytoskeleton was the first target investigated during Listeria infection. Microfilaments and cell-to-cell junctions.
- Listeria the first multifactorial model: internalization, endosomal escape, actin comets, autophagy and mitochondria fragmentation
- Yersinia and invasive phagocytosis in epithelia and impairment the phagocytic capacities of macrophages/cell death. T3SS and YOPs. Differences of enteropathogenic Yersinia spp with Y. pestis
- Macropinocytic internalization of Shigella and Salmonella. T3SS.
- Shigella virulence determinants, intracellular trafficking, escape to autophagy and local inflammation.
- Salmonella SPI-1 and 2, invasion and establishment of intracellular niches. Overcoming microbiota and the inflammatory response. Differences between typhoid and non typhoid serovars.
