Resumen
Las coinfecciones bacterianas, junto con el virus del papiloma humano (VPH), aumentan significativamente el riesgo de cáncer de cuello uterino. Dirigirse a estos microbios junto con el VPH es crucial para estrategias de prevención eficaces.
Área de la Ciencia:
- Ginecología
- Oncología
- Microbiología
Sus antecedentes:
- El cáncer de cuello uterino es un importante problema de salud mundial, impulsado principalmente por el virus del papiloma humano (VPH) de alto riesgo.
- Las coinfecciones bacterianas son cada vez más reconocidas como contribuyentes significativos a la persistencia del VPH y la carcinogénesis cervical.
Objetivo del estudio:
- Revisar el papel de las coinfecciones bacterianas en la exacerbación de la persistencia del VPH y la promoción de lesiones cervicales.
- Destacar la necesidad de estrategias integradas centradas en el microbioma en la prevención del cáncer de cuello uterino.
Principales métodos:
- Revisión sistemática de metaanálisis y estudios recientes sobre VPH y coinfecciones bacterianas.
- Análisis de datos que vinculan patógenos específicos (Chlamydia trachomatis, Mycoplasma genitalium, Gardnerella vaginalis, microbiota anaeróbica) con la persistencia del VPH y las lesiones cervicales.
- Examen del impacto de la depleción de Lactobacillus en la carga viral del VPH y la progresión de la neoplasia intraepitelial cervical (NIC).
Principales resultados:
- Las coinfecciones bacterianas con patógenos como Chlamydia trachomatis, Mycoplasma genitalium, Gardnerella vaginalis y microbiota anaeróbica aumentan marcadamente el riesgo de infección persistente por VPH y lesiones cervicales.
- Estos microbios alteran las barreras epiteliales, inducen inflamación crónica y mejoran la actividad oncogénica de las proteínas E6/E7 del VPH.
- Los microbiomas vaginales con depleción de Lactobacillus se asocian con cargas de VPH más altas y un mayor riesgo de progresión a CIN2+.
Conclusiones:
- Se respalda un modelo de doble patógeno, que involucra tanto al VPH como a las bacterias, para la carcinogénesis cervical.
- La integración del análisis y las intervenciones del microbioma en las estrategias de prevención del cáncer de cuello uterino es esencial, particularmente en regiones con cobertura limitada de vacunación y detección del VPH.

In 1928, bacteriologist Frederick Griffith worked on a vaccine for pneumonia, which is caused by Streptococcus pneumoniae bacteria. Griffith studied two pneumonia strains in mice: one pathogenic and one non-pathogenic. Only the pathogenic strain killed host mice.
Griffith made an unexpected discovery when he killed the pathogenic strain and mixed its remains with the live, non-pathogenic strain. Not only did the mixture kill host mice, but it also contained living pathogenic bacteria that...

01:30Bacterial Signaling
41.3K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

Unlike eukaryotes, bacteria use a single RNA Polymerase (RNAP) to transcribe all genes. The different subunits of bacterial RNAPhave distinct functions. The multisubunit structure of the bacterial RNAP helps the enzyme to maintain catalytic function, facilitate assembly, interact with DNA and RNA, and self-regulate its activity.
In most genes, the transcription site is a single base present upstream of the coding sequence. Though RNAP is a catalytically efficient enzyme, it does not recognize...

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

01:53Bacterial Transcription
36.6K
RNA polymerase (RNAP) carries out DNA-dependent RNA synthesis in both bacteria and eukaryotes. Bacteria do not have a membrane-bound nucleus. So, transcription and translation occur simultaneously, on the same DNA template.
Transcription can be divided into three main stages, each involving distinct DNA sequences to guide the polymerase. These are:
