What are the different types of compact discs?

Types of Compact Disks. There are three types of CDs available: CD-R (Compact Disc – Recordable): This type of compact disc can be written only once and can not ereased. CD-ROM (Compact Disk-Read Only Memory): This disks are read once, after read it is use as a ROM, that is cannot be updated later.

What is CD RW?

CD-RW (Compact Disc-ReWritable): This type of compact disc can be written multiple times and can be erased also, like Pendrive.

What is CD-R recordable?

CD-R (Compact Disc – Recordable): This type of compact disc can be written only once and can not ereased.

What is the thickness of a CD?

The standard diameter of a CD is 120mm and thickness is 1.2mm. The main body of the CD is made of hard plastic known as polycarbonate with a reflective metallic layer. This layer is coated with metallic acrylic plastic. This metal is aluminum. In this layer, the data are stored using the laser light which reflects the coated layer for reading and writing the data. The data is read in the form of pits, each pit is of 0.83-micrometre and the data is arranged as spiral track from the disc’s inner hole to its outer edge, because the CD is of circular shape.

What is CD system?

Cluster of Differentiation. The CD system is commonly used as cell markers in immunophenotyping, allowing cells to be defined based on what molecules are present on their surface. These markers are often used to associate cells with certain immune functions.

What is a CD combination?

This CD combination typically corresponds to a stem cell, as opposed to a fully differentiated endothelial cell. Some cell populations can also be defined as hi, mid or low (alternatively bright, mid or dim ), indicating an overall variability in CD expression, particularly when compared to other cells being studied.

What is the role of CD4 and CD8 in the cell surface?

In the example of CD4 & CD8, these molecules are critical in antigen recognition. Others (e.g., CD135) act as cell surface receptors for growth factors. Recently, the marker CD47 was found to have anti-phagocytic signals to macrophages and inhibits natural killer (NK) cells.

What are CD4 and CD8 used for?

Two commonly used CD molecules are CD4 and CD8, which are, in general, used as markers for helper and cytotoxic T cells , respectively. These molecules are defined in combination with CD3+, as some other leukocytes also express these CD molecules (some macrophages express low levels of CD4; dendritic cells express high levels of CD8). Human immunodeficiency virus (HIV) binds CD4 and a chemokine receptor on the surface of a T helper cell to gain entry. The number of CD4 and CD8 T cells in blood is often used to monitor the progression of HIV infection.

What is cluster of differentiation?

The cluster of differentiation (also known as cluster of designation or classification determinant and often abbreviated as CD) is a protocol used for the identification and investigation of cell surface molecules providing targets for immunophenotyping of cells. In terms of physiology, CD molecules can act in numerous ways, often acting as receptors or ligands important to the cell. A signal cascade is usually initiated, altering the behavior of the cell (see cell signaling ). Some CD proteins do not play a role in cell signaling, but have other functions, such as cell adhesion. CD for humans is numbered up to 371 (as of 21 April 2016#N#[update]#N#).

What are CD molecules?

While CD molecules are very useful in defining leukocytes, they are not merely markers on the cell surface. While only a fraction of known CD molecules have been thoroughly characterised, most of them have an important function. In the example of CD4 & CD8, these molecules are critical in antigen recognition.

For example, a " CD34 +, CD31 −" cell is one that expresses CD34, but not CD31.

What is CD4 in biology?

Image of CD4 co-receptor binding to MHC (Major Histocompatibility Complex) non-polymorphic region. In molecular biology, CD4 ( cluster of differentiation 4) is a glycoprotein that serves as a co-receptor for the T-cell receptor (TCR).

What is the CD4 gene?

What is the CD4 receptor?

Schematic representation of CD4 receptor. Like many cell surface receptors/markers, CD4 is a member of the immunoglobulin superfamily . It has four immunoglobulin domains (D 1 to D 4) that are exposed on the extracellular surface of the cell: D 1 and D 3 resemble immunoglobulin variable (IgV) domains. D 2 and D 4 resemble immunoglobulin constant ...

How does HIV-1 use CD4?

HIV-1 uses CD4 to gain entry into host T-cells and achieves this through its viral envelope protein known as gp120. The binding to CD4 creates a shift in the conformation of gp120 allowing HIV-1 to bind to a co-receptor expressed on the host cell. These co-receptors are chemokine receptors CCR5 or CXCR4. Following a structural change in another viral protein ( gp41 ), HIV inserts a fusion peptide into the host cell that allows the outer membrane of the virus to fuse with the cell membrane .

Where is CD4 found?

CD4 is found on the surface of immune cells such as T helper cells, monocytes, macrophages, and dendritic cells. It was discovered in the late 1970s and was originally known as leu-3 and T4 ...

CD4 continues to be expressed in most neoplasms derived from T helper cells. It is therefore possible to use CD4 immunohistochemistry on tissue biopsy samples to identify most forms of peripheral T cell lymphoma and related malignant conditions. The antigen has also been associated with a number of autoimmune diseases such as vitiligo and type I diabetes mellitus.
