Epithelial Tissues and Their Functions01:23

Epithelial Tissues and Their Functions

41.0K
Epithelial tissues are large sheets of cells covering all of the surfaces of the body. These surfaces can be internal or external, for example, skin, airways, the digestive tract, the urinary system, and the reproductive system. Hollow organs and body cavities that do not connect to the body's exterior, including blood vessels and serous membranes, are lined by epithelial tissue known as the endothelium.
Epithelial tissues provide the body's first line of protection from physical,...

Lung Capacity

56.4K
The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

Transgenic Plants02:50

Transgenic Plants

8.7K
Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Induced Pluripotent Stem Cells

28.1K
Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...

T Cell Types and Functions01:24

T Cell Types and Functions

2.5K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Area of Science:

  • Pulmonary immunology
  • Epithelial biology
  • Genetic engineering

Background:

  • The lung epithelium is a critical component of the innate immune system, serving as a physical barrier and producing defense proteins.
  • It plays a dual role as both a protector and a target in lung diseases.
  • Understanding gene function in the lung epithelium is vital for deciphering pulmonary defense mechanisms.

Purpose of the Study:

  • To describe effective genetic strategies for interrogating the lung epithelium in mice.
  • To enable spatiotemporal targeting of gene expression within the lung epithelium.
  • To facilitate the study of genes involved in pulmonary defense.

Main Methods:

  • Development of tissue-/cell-specific genetic targeting strategies.
  • Implementation of inducible control for gene expression.
  • Methods for spatiotemporal control of gene expression in the lung epithelium.

Main Results:

  • Established effective genetic strategies for targeting the lung epithelium in mice.
  • Enabled precise control over gene expression timing and location.
  • Provided tools to investigate gene significance in pulmonary defense.

Conclusions:

  • Genetic targeting of the lung epithelium is feasible and crucial for research.
  • Spatiotemporal control of gene expression enhances the study of lung defense.
  • These methods advance our understanding of lung pathologies and host defense.
