Overview of Cell Signaling01:23

Overview of Cell Signaling

21.7K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate with the environment.
Cells respond to many types of information, often through receptor proteins positioned on the membrane. For example, skin cells respond to and transmit touch...

Cell-surface Signaling

52.5K
Hormones—or any molecule that binds to a receptor, known as a ligand—that are lipid-insoluble (water-soluble) are not able to diffuse across the cell membrane. In order to be able to affect a cell without entering it, these hormones bind to receptors on the cell membrane. When a first messenger, a hormone, binds to a receptor, a signal cascade is set off, causing second messengers, proteins inside the cell, to become activated, resulting in downstream effects.

What are Membranes?

15.4K
A cell's plasma membrane demarcates the cell's borders and determines the nature of its interaction with the environment. Cells exclude certain substances, take in others, and excrete some others in controlled quantities. The plasma membrane must be flexible to allow certain cells, such as red and white blood cells, to change their shape while passing through narrow capillaries. These are the more obvious plasma membrane functions. In addition, the plasma membrane's surface carries...

Cell Signaling in Plants01:25

Cell Signaling in Plants

5.8K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

Cell Adhesion Molecules - Types and Functions

7.6K
Cell adhesion molecules (CAMs) are pivotal to multicellularity and the coordinated functioning of tissues and organ systems. They enable physical interactions between cells and provide mechanical strength to tissues. They also function as receptors for signal transmission across the plasma membrane. The CAMs are broadly classified into four families - integrins, cadherins, selectins, and immunoglobulin-like CAMs (IgCAMs).
CAM Families
The Integrin family of proteins is primarily  involved...

    • Developmental Biology
    • Cell Biology
    • Evolutionary Biology

    Background:

    • Morphogenesis involves the segregation of homogeneous cell populations into distinct cell lines.
    • Each cell line possesses a unique developmental program.
    • Cellular recognition is crucial for the proper unfolding of these programs.

    • Experiments were conducted to demonstrate the necessity of specific surface properties for cell recognition.
    • The study describes experimental evidence supporting the proposed hypothesis.

    Main Results:

    • Cells within the same line recognize each other through specific surface properties.
    • Cells differentiate between their own type and other cell types via surface recognition.
    • Experimental data supports the proposed model of cell-cell recognition.

    Conclusions:

    • Specific surface properties are essential for cell recognition and the segregation of cell lines during morphogenesis.
    • A phylogenetic link is hypothesized between the cell-cell recognition system and the emergence of sexual reproduction.
