Mice Deficient for the Ecto-Nicotinamide Adenine Dinucleotide Glycohydrolase CD38 Exhibit Altered Humoral Immune Responses

TLDR
It is shown that CD38 is not required for hematopoietic stem cells as well as on committed progenitors, and in vivo physiological function(s) of this novel class of ectoenzyme are investigated, suggesting thatCD38 may play an important role in vivo in regulating humoral immune responses.

Evolution and Function of the ADP Ribosyl Cyclase/CD38 Gene Family in Physiology and Pathology

TL;DR: CD38 is a powerful disease marker for human leukemias and myelomas, is directly involved in the pathogenesis and outcome of human immunodeficiency virus infection and chronic lymphocytic leukemia, and controls insulin release and the development of diabetes.

Lyn tyrosine kinase: accentuating the positive and the negative.

TL;DR: The outcomes of altered Lyn activity within the framework of B cell development and differentiation and the circumstances that appear to dictate the outcome are reviewed.

New functions of a long-known molecule. Emerging roles of NAD in cellular signaling.

TL;DR: The first group of reactions leads to the synthesis of an unusual cyclic nucleotide, cyclic ADP-ribose (cADPR), which has been reported to be potent intracellular calcium-mobilizing agents and in concert with inositol 1,4,5-trisphosphate, they participate in cytosolic calcium regulation by releasing calcium from intrace cellular stores.
Journal ArticleDOI

Regulation of intracellular levels of NAD: a novel role for CD38.

TL;DR: Tissue levels of NAD in CD38 deficient mice are 10- to 20-fold higher than in wild-type animals, and NADase activity in the plasma membrane, mitochondria, sarcoplasmic reticulum, and nuclei is essentially absent, which support the novel concept that CD38 is a major regulator of cellular NAD levels.

Discrete stages of human intrathymic differentiation: Analysis of normal thymocytes and leukemic lymphoblasts of T-cell lineage

TL;DR: It is suggested that is it now possible to define stages of T-cell differentiation that can be related to T- cell malignancies in humans.

Sequential generations of hematopoietic colonies derived from single nonlineage-committed CD34+CD38- progenitor cells.

TL;DR: Direct evidence is provided for the existence of a single class of progenitors with extensive proliferative capacity in human BM and an experimental approach for their purification, manipulation, and further characterization is provided.

T Cell-Independent Antigens Type 2

TL;DR: Evidence demonstrating that B cell activation via TI stimuli does not play merely a permissive role in allowing for cell cycle entry and enhanced responsiveness to other stimuli is presented, rather, the nature of the B cell activating signal is critical in determining the quantitative and qualitative profile of Ig isotype production.
Journal ArticleDOI

The role of helper T cell products in mouse B cell differentiation and isotype regulation.

TL;DR: In this article, the authors summarize the efforts to define the specific helper T cells or lymphokines which transmit regulatory signals to B cells, and to clarify the individual events influenced by these signals.
