What is Polytypic plasma cells?

What is Polytypic plasma cells?

Monotypic refers to them being either kappa or lambda light chain restricted (as opposed to normal polytypic plasma cells which have a mix of kappa and lambda expressing plasma cells) In Symptomatic Plasma Cell Myeloma, patients present with one or more of the “CRAB” findings: “C” for hyperCalcemia, “R” for renal …

What are polyclonal plasma cells?

In healthy individuals, plasma cells produce proteins called “polyclonal immunoglobulins.” These are a collection of antibodies that protect the body against all kinds of different invading viruses, bacteria or other infectious agents (antigens).

What does Polytypic mean?

Definition of polytypic : represented by several or many types or subdivisions a polytypic species of organism.

What are Mott cells?

Mott cells are plasma cells defective in immunoglobulin (Ig) secretion. They display this defect by accumulating Ig in the rough endoplasmic reticulum, detectable by Ig+ intracellular inclusion.

Does myeloma cause tumors?

In multiple myeloma, abnormal plasma cells (myeloma cells) build up in the bone marrow and form tumors in many bones of the body. These tumors may keep the bone marrow from making enough healthy blood cells.

What does IgG Kappa mean?

The most common type of myeloma is IgG kappa. In IgG kappa myeloma, the myeloma cells produce an immunoglobulin made from two IgG heavy chains bound to two kappa light chains. About 15% of patients have light chain myeloma. In this type of myeloma, the myeloma cells secrete only light chain protein and no heavy chains.

What blood results indicate myeloma?

Blood chemistry tests

• Creatinine levels show how well your kidneys are working. High levels mean that the kidneys are not functioning well.
• Albumin is a protein found in the blood. Low levels can be seen in myeloma.
• Calcium levels may be high in people with advanced myeloma.

What are the characteristics of a monotypic species?

Typically, members of a monotypic species classification live within close proximity to one another and share high degrees of biological similarity. Because no real distinction can be made among the population members, it is considered monotypic.

Is there a B‐cell population with monotypic light chain expression in CSF?

A B‐cell population with monotypic light chain expression was identified in CSF specimens from three patients whose subsequent clinical and radiologic evaluation provided no evidence for lymphoma. In all three patients, a diagnosis of multiple sclerosis was ultimately rendered upon completion of the clinical evaluation.

Is the hyacinth macaw monotypic or polytypic?

Species can be monotypic or polytypic depending on the classification of the species into subspecies. The Hyacinth macaw is an example of a Monotypic species as it is not divided into any subspecies. In scientific terms, a species is a group of living organisms that belong to the lowest taxonomic level of the biological classification hierarchy.

What is the difference between small mononuclear cells and Kappa-bearing B cells?

B cells with the low forward (FSC) and side (SSC) scatter characteristic of small mononuclear cells comprised a mixture of kappa- and lambda-bearing cells, without evidence of light chain restriction, whereas in all three cases, kappa-bearing B cells comprised a preponderance of cells with increased FSC and SSC (Table 1, Fig. 1 ).
