Summary
Dendritic cells (DCs) are key immune cells. This review covers the development and regulation of diverse DC subsets in various tissues, crucial for immunity and tolerance.
Area of Science:
- Immunology
- Cell Biology
Background:
- Dendritic cells (DCs) are specialized antigen-presenting cells critical for initiating immune responses and maintaining self-tolerance.
- The diverse functions of DCs are attributed to distinct subsets characterized by unique cell surface markers and tissue distribution.
Purpose of the Study:
- To provide a comprehensive review of the development and homeostasis of dendritic cells.
- To explore the heterogeneity of DC subsets in both lymphoid and nonlymphoid tissues.
Main Methods:
- Literature review of existing research on dendritic cell biology.
- Synthesis of data on DC development, subset identification, and tissue localization.
Main Results:
- Dendritic cells exhibit significant heterogeneity, with specialized subsets residing in various anatomical locations.
- Understanding DC subsets is essential for comprehending their roles in immunity and tolerance.
Conclusions:
- The development and homeostasis of distinct dendritic cell subsets are fundamental to immune system function.
- Further research into DC heterogeneity will illuminate mechanisms of immunity and tolerance.

01:16What is Homeostasis?
53.2K
Maintaining homeostasis requires that the body continuously maintain its internal conditions. Each physiological condition has a particular set point, from body temperature to blood pressure to levels of certain nutrients. A set point is the physiological value around which the normal range fluctuates. A normal range is a restricted set of values that is optimally healthful and stable. For example, the set point for normal human body temperature is approximately 37°C (98.6°F).

01:31pH Homeostasis
18.4K
Acid-base homeostasis is essential for maintaining normal physiological activities in humans. The pH of various body fluids is strictly regulated because it is critical for the optimal activity of enzymes involved in metabolic reactions. Enzymes are basically proteins, so, any significant change in pH can affect their structure and activity. In humans, pH is regulated using three primary mechanisms— chemical buffer systems, respiratory regulation, and renal regulation.

01:21Skeleton and Calcium Homeostasis
5.9K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

01:23Neurons: The Cell Body and the Dendrites
6.7K
A typical nerve cell comprises three main components: the cell body, dendrites, and the axon. The cell body, also known as the soma or perikaryon, serves as the central biosynthetic hub housing a nucleus surrounded by cytoplasm containing organelles commonly found in most cells. Notably, Nissl bodies, clusters of the rough endoplasmic reticulum and free ribosomes responsible for protein synthesis, are distinctive features of the neuronal cell body. As neurons age, aggregates of a brown pigment...

01:02Glucose Homeostasis: Regulation of Blood Glucose
4.0K
Carbohydrates consumed through foods are converted into glucose, a crucial energy source for the body. In the prandial state, high blood glucose levels stimulate the secretion of insulin from the pancreas. Insulin inhibits hepatic glucose production and stimulates glucose uptake and metabolism by muscle and adipose tissue. The excess glucose is converted into glycogen and stored in the liver and muscles.
During fasting, when blood glucose levels are low, the pancreas secretes glucagon. it...

01:27Glucose Homeostasis: Pancreatic Islets and Insulin Secretion
2.2K
The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
