Sankar Ghosh, professor of immunobiology at Yale University, explores the regulation of gene expression in developing and differentiating lymphocytes.
Analysis using ImmuneSigDB identified signatures induced in activated myeloid cells and differentiating lymphocytes that were highly conserved between humans and mice.
This model system was selected because methods for activating or differentiating lymphocytes are well understood and the cells can be readily cultured.
Infectious bursal disease virus replicates in differentiating lymphocytes of the Bursa of Fabricius, causing the immunosuppressive and often fatal condition called infectious bursal disease (IBD) or Gumboro.
We have identified the MD lymphoma microenvironment as predominantly T-reg-like [ 6] but did not differentiate which lymphocytes were contributing to the phenotype.
Loss of programmed death 1 reactivity did not correlate with diffuse areas, progression, or the ability to differentiate nodular lymphocyte predominant Hodgkin lymphoma from T-cell and histiocyte-rich large B-cell lymphoma.
First, after lysis of red blood cells (RBCs), the tungsten-halogen based optical system of the MPO channel measures cell size by forward light scatter, and stain intensity by absorbance, thereby counting and differentiating granulocytes, lymphocytes, and monocytes based on their size and MPO content.
While thus sequestered, the lymphocytes differentiate, or acquire the capabilities to perform specialized tasks.
Some of these cells travel to the thymus, where they multiply and differentiate into T lymphocytes, or T cells.
Multiple myeloma (MM) is an incurable hematological malignancy that results from genetic mutations that occur during the process whereby B lymphocytes differentiate into plasma cells (Kyle and Rajkumar, 2008).
