Summary
Stem cell transplantation in DOCK8-deficient individuals restored the skin microbiome balance. This highlights how crucial the immune system is for maintaining healthy skin microbial communities.
Area of Science:
- Immunology
- Microbiome research
- Genetics
Background:
- Inborn errors of immunity (IEI) significantly impair host-microbe interactions.
- DOCK8 deficiency is a primary immunodeficiency affecting multiple systems.
- The skin microbiome plays a critical role in cutaneous immunity and health.
Purpose of the Study:
- To investigate the impact of immune reconstitution on the skin microbiome in DOCK8-deficient patients.
- To understand the relationship between immune function and microbial ecology in the skin.
Main Methods:
- Analysis of skin microbiome composition in DOCK8-deficient individuals before and after stem cell transplantation.
- Assessment of immune reconstitution markers post-transplantation.
Main Results:
- Immune reconstitution following stem cell transplantation led to a significant rebalancing of the skin microbiome in DOCK8-deficient individuals.
- Restored immune function correlated with a healthier and more diverse cutaneous microbial profile.
Conclusions:
- Immunity is a key determinant of skin microbial community structure.
- Stem cell transplantation can restore immune function and positively influence the skin microbiome in primary immunodeficiency disorders.
- Targeting immune reconstitution may be a therapeutic strategy for managing microbiome dysbiosis in IEI.

01:23Renewal of Intestinal Stem Cells
2.7K
The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the...

01:12Renewal of Skin Epidermal Stem Cells
2.6K
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...

01:33Adult Stem Cells
30.6K
Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

01:19Clinical Applications of Epidermal Stem Cells
2.8K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

01:26Stem Cell Niche
5.3K
The stem cell niche is the dynamic microenvironment where stem cells reside. Inside these niches, the cells may remain undifferentiated, undergo high self-renewal, or become lineage-specific progenitors. Stem cells coexist with other niche cells, such as stromal cells. They also interact closely with the ECM. Cell-cell and cell-matrix communication occur via adhesion molecules or soluble factors that signal the stem cells and determine their fate. Stromal cells also provide survival signals to...

01:23Anatomy of the Intestines
74.0K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...
