Summary
Schistosome infection impairs hematopoietic stem cell (HSC) function and alters red blood cell production. This study reveals key impacts of helminth infections on the immune system and blood cell development.
Area of Science:
- Immunology
- Hematology
- Parasitology
Background:
- Helminth infections are prevalent globally, yet their effects on hematopoietic stem cells (HSCs) remain poorly understood.
- Schistosomiasis, caused by *Schistosoma mansoni* flatworms, affects over 200 million people, often leading to anemia and splenomegaly.
Approach:
- This study investigated the hematopoietic system's response to *Schistosoma mansoni* infection in mice.
- Researchers analyzed hematopoietic cell populations in bone marrow, spleen, liver, thymus, and blood.
- HSC function was assessed through serial transplantation.
Key Points:
- Schistosome infection significantly impaired bone marrow HSC function.
- Functional HSCs were identified within the infected liver.
- Bone marrow erythropoiesis was inhibited, while spleen erythropoiesis was enhanced, correlating with clinical schistosomiasis symptoms.
Conclusions:
- This research elucidates the complex hematopoietic alterations induced by schistosomiasis.
- The findings highlight critical impairments in HSC function and erythropoiesis during helminth infection.
- Understanding these mechanisms is crucial for managing schistosomiasis-related complications.

3.3K
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

01:20Overview of Hematopoiesis
4.4K
Hematopoiesis, or blood cell production, is a vital biological process that begins early in embryonic development and continues throughout life. This process generates the various types of cells found in blood, including red blood cells, white blood cells, and platelets from hematopoietic stem cells (HSCs).
Developmental Phases of Hematopoiesis
Initially, HSCs are formed in the embryonic yolk sac, a critical site for early blood cell production. These stem cells subsequently migrate to other...

The process of blood cell formation is called hematopoiesis. Hematopoiesis starts early during development, on the seventh day of embryogenesis. This phase of hematopoiesis is called the primitive wave, wherein the extraembryonic yolk sac allows the production of erythroid cells and endothelial cells from a common precursor called hemangioblast. The erythroid cells provide oxygen to support the growth of the rapidly dividing embryo. Hemangioblasts later develop into hematopoietic stem cells or...

01:28Role of Hematopoietic Growth Factors
1.5K
Hematopoietic growth factors are molecules that regulate the differentiation rate of hematopoietic stem cells (HSCs). Erythropoietin (EPO), primarily produced by the kidneys, plays a crucial role in erythrocyte production. When oxygen levels in the blood are low, EPO is released into the bloodstream, reaching the bone marrow, where it stimulates HSCs to differentiate and mature into erythrocytes, which are vital for oxygen transport.

01:19Multipotency of Hematopoietic Stem Cells
3.2K
The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...

01:27Disorders of Erythrocytes
1.0K
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
