Summary
Xenophagy, a cellular defense against pathogens, is often subverted by invading bacteria. This review details bacterial infection mechanisms and how they disrupt xenophagy for persistent colonization.
Area of Science:
- Cell Biology
- Immunology
- Microbiology
Background:
- Autophagy is a cellular process for degrading components to maintain homeostasis.
- Xenophagy, a specialized autophagy, acts as an innate immune response against intracellular pathogens.
- Pathogens have evolved mechanisms to evade or disable xenophagy, enabling intracellular survival.
Purpose of the Study:
- To review the general mechanisms of intracellular bacterial infections.
- To summarize the process of xenophagy.
- To focus on the interplay between bacterial pathogens and xenophagy.
Main Methods:
- Literature review of existing research on autophagy, xenophagy, and bacterial pathogenesis.
- Synthesis of current knowledge on host-pathogen interactions at the cellular level.
Main Results:
- Intracellular bacteria employ diverse strategies to counteract xenophagy.
- Disruption of xenophagy by pathogens facilitates their persistence within host cells.
- Understanding these mechanisms is crucial for developing new therapeutic strategies.
Conclusions:
- The battle between xenophagy and intracellular bacteria highlights a critical aspect of host-pathogen dynamics.
- Further research into pathogen evasion tactics can reveal novel targets for antimicrobial therapies.

5.7K
Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...

Once a ligand binds to a receptor, the signal is transmitted through the membrane and into the cytoplasm. The continuation of a signal in this manner is called signal transduction. Signal transduction only occurs with cell-surface receptors, which cannot interact with most components of the cell, such as DNA. Only internal receptors can interact directly with DNA in the nucleus to initiate protein synthesis. When a ligand binds to its receptor, conformational changes occur that affect the...

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...

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...

Lipid-soluble hormones diffuse across the plasma and nuclear membrane of target cells to bind to their specific intracellular receptors. These receptors act as transcription factors that regulate gene expression and protein synthesis in the target 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...
