The human microbiome in hematopoiesis and hematologic disorders

Area of Science:

• Microbiology
• Human Physiology
• Genomics

Background:

• Humans exist in symbiosis with a diverse microbial ecosystem, the microbiota.
• Understanding the microbiota's composition and function is crucial for human health.
• Key questions involve identifying microbial species, their functions, and interaction mechanisms.

Purpose of the Study:

• To review current efforts in characterizing the human microbiota.
• To summarize molecular technologies used for microbiota analysis.
• To explore microbiota interactions with humans, particularly in hematopoiesis and hematologic diseases.

Main Methods:

• Review of recent studies on microbiota composition in healthy and diseased individuals.
• Summary of molecular techniques: 16S ribosomal RNA sequencing and shotgun metagenomic sequencing.
• Exploration of known human-microbiota interactions.

Main Results:

• Recent advances have improved the description of microbiota in various health states.
• Molecular technologies enable detailed enumeration of microbial community structures.
• Specific interactions between the microbiota and human systems, including hematopoiesis, are being elucidated.

Conclusions:

• The human microbiota plays a significant role in health and disease.
• Advanced sequencing technologies are vital for microbiota research.
• Further investigation into microbiota-host interactions is essential, especially concerning blood and blood disorders.
