$\begingroup$ Yes, in Robbin's Basic Pathology, while describing inflammatory process of several diseases, it is mentioned that there is presence of both plasma cells as well as lymphocytes in the affected tissue. So that raises the question, why are plasma cells and …

2016年10月11日 · The B-cell lineage precursor of non-dividing plasma cells, which has the capacity to divide and that has migratory potential. Once it matures as a plasma cell, it is out in the blood secreting soluble immunoglobulins or antibodies. Another important definition to mentioned here would be of antibody secreting cells. Antibody-secreting cells

I understand that the cell class switches to change the type of immunoglobulin it is producing. The B-cell produces the membrane bound B-cell receptor (BCR) while the plasma cell produces the the secreted form of Ig, the antibody. Now, the isotypes are different in their constant regions and I'm assuming switching only matters if it is an antibody.

2015年4月19日 · When sorting cell populations it is possible to use either magnetic-activated cell sorting or fluorescence-activated cell-sorting (FACS). I am wondering when you would choose either technique and what the pro's and con's of each technique are. As FACS sorts cells one by one, I can imagine magnetic-activated cell sorting is a faster process.

- The affix-cyte means cell; - The affix -blast means a germ (bud) cell or a cell that produces (building) materials. Background Cells are denoted as -cytes. There are many of them, e.g. melanocytes in the skin and chondrocytes in the cartillage. Germ cells are denoted as -blasts.

2019年10月22日 · When a naïve or memory B cell is activated by antigen (with the aid of a helper T cell), it proliferates and differentiates into an antibody-secreting effector cell. Such cells make and secrete large amounts of soluble (rather than membrane-bound) antibody, which has the same unique antigen-binding site as the cell-surface antibody that served ...

2016年8月5日 · To expand a bit: After T-cell dependant B-cell activation through an antigen to the B-cell receptor, the B-cell divides into a few very short-lived plasma cells and centroblasts. The latter undergo somatic hypermutation and rapid cell expansion to result in many different B-cells which produce similar, but different antibodies).

2016年11月29日 · $\begingroup$ Polar molecules needs electrochemical gradient and protein carrier. ...whereas non polar molecules needs kinetic energy and these molecule continuously bouncing to come out from the cell membrane through the channel provide by lipoprotein structure of cell membrane and concentration gradient also effective for movement of ...

2016年6月9日 · Compartmentalising the cell has lots of advantages and purposes. In Koshland's 2002 essay, compartmentalisation was described as one of the seven fundamental pillars of life. Broadly speaking, membranes create different sets of …

2017年9月12日 · Yet, in a current college course, the textbook ("Molecular Biology of the Cell 6th" by Bruce Alberts et al.) says that cholesterol reduces the mobility of the first few CH2 groups of a phospholipid's two fatty acid chains.
