The acute environment, rather than T cell subset pre-commitment, regulates expression of the human T cell cytokine amphiregulin.

Journal:PLoS One
PubMed ID:22720031
'Cytokine expression patterns of T cells can be regulated by pre-commitment to stable effector phenotypes, further modification of moderately stable phenotypes, and quantitative changes in cytokine production in response to acute signals. We showed previously that the epidermal growth factor family member Amphiregulin is expressed by T cell receptor-activated mouse ... More
IL-2-dependent adaptive control of NK cell homeostasis.

'Activation and expansion of T and B lymphocytes and myeloid cells are controlled by Foxp3(+) regulatory T cells (T reg cells), and their deficiency results in a fatal lympho- and myeloproliferative syndrome. A role for T reg cells in the homeostasis of innate lymphocyte lineages remained unknown. Here, we report ... More
Host immunity and pathogen strain contribute to intestinal disaccharidase impairment following gut infection.

Journal:J Immunol
PubMed ID:21873528
'Infection or other inflammatory insults in the small intestine often result in reduced disaccharidase enzyme levels. Using a mouse model of giardiasis, we examined the role of host immunity and pathogen virulence in mediating disaccharidase deficiency postinfection (p.i.). C57BL/6J mice were infected with two strains, WB and GS, of the ... More
Functional recovery after peripheral nerve injury is dependent on the pro-inflammatory cytokines IL-1ß and TNF: implications for neuropathic pain.

Journal:J Neurosci
PubMed ID:21880915
'IL-1ß and TNF are potential targets in the management of neuropathic pain after injury. However, the importance of the IL-1 and TNF systems for peripheral nerve regeneration and the mechanisms by which these cytokines mediate effects are to be fully elucidated. Here, we demonstrate that mRNA and protein levels of ... More
Stemness of B-cell progenitors in multiple myeloma bone marrow.
Authors:Boucher K, Parquet N, Widen R, Shain K, Baz R, Alsina M, Koomen J, Anasetti C, Dalton W, Perez LE,
Journal:Clin Cancer Res
PubMed ID:22988056
In myeloma, B cells and plasma cells show a clonal relationship. Clonotypic B cells may represent a tumor-initiating compartment or cancer stem cell responsible for minimal residual disease in myeloma. We report a study of 58 patients with myeloma at time of diagnosis or relapse. B cells in bone marrow ... More
