Summary
Immune cells reprogram through epigenetic and microRNA (miRNA) regulation during bacterial infections. Pathogens exploit these mechanisms to evade host immunity, highlighting potential therapeutic targets.
Area of Science:
- Immunology
- Molecular Biology
- Genetics
Background:
- Immune cell reprogramming is crucial for host-pathogen interactions and immune evasion.
- Epigenetic and microRNA (miRNA) regulation plays a significant role in these cellular processes.
- Understanding these regulatory mechanisms is vital for developing effective treatments against bacterial infections.
Purpose of the Study:
- To review the role of epigenetic and miRNA control in the host immune system during bacterial infections.
- To highlight how pathogens utilize these regulatory pathways for immune evasion.
- To emphasize the potential of epigenetic and miRNA mapping in identifying therapeutic targets.
Main Methods:
- Literature review of studies on epigenetic and miRNA regulation in host-pathogen interactions.
- Analysis of examples involving bacterial infections and their impact on host immunity.
- Discussion of recent advancements in techniques for studying epigenetic and miRNA functions.
Main Results:
- Epigenetic modifications and miRNAs are key regulators of host immune responses during bacterial infections.
- Pathogens actively manipulate host epigenetic and miRNA machinery to evade immune detection and clearance.
- Specific examples illustrate the intricate interplay between host and pathogen at the molecular level.
Conclusions:
- Epigenetic and miRNA mechanisms are central to host immune responses and pathogen evasion strategies.
- Global mapping of epigenetic and miRNA profiles in host-pathogen interactions can reveal critical cellular functions.
- This research area holds significant promise for identifying novel therapeutic targets for infectious diseases.

The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

01:22Introduction to the Human Microbiota
60
Microorganisms colonize various regions of the human body, including the mouth, nasal passages, throat, stomach, intestines, urogenital tract, and skin. The total number of microbial cells is estimated to range from 10¹³ to 10¹⁴—comparable to, or exceeding, the number of human somatic cells. This host–microbiome relationship has led to the conceptualization of humans as supraorganisms, wherein microbial communities perform vital roles in development, immunity,...

The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more...

Parasitism is a form of microbial interaction in which parasitic microbes exploit a host organism for nutrients and shelter, often at the host's expense. Unlike mutualistic relationships, where both organisms benefit, parasitism benefits only the parasite and harms the host.Classification of ParasitesMicrobial parasites are broadly classified based on their location relative to the host.Ectoparasites remain on the host’s surface, such as the skin or outer tissues, drawing nutrients...
