Abstract:
Abstract Tumor necrosis factor-alpha (TNF-alpha) is a bifunctional regulator of hematopoiesis, and its cellular responses are mediated by two distinct cell surface receptors. TNF-alpha generally inhibits the growth of primitive murine hematopoietic progenitor cells (Lin-Scal+) in response to multiple cytokine combinations, and the p75 TNF receptor is essential in signaling such inhibition. In the present study we show the reverse phenomenon in that TNF-alpha on the same progenitor cell population in combination with stem cell factor (SCF) and interleukin-7 (IL-7) through the p55 TNF receptor c

Abstract Abstract 2767 Schimke immuno-osseous dysplasia (SIOD) is an autosomal recessive, incompletely penetrant, childhood disorder associated with biallelic loss-of-function mutations of SMARCAL1 (swi/snf-related matrix-associated actin-dependent regulator of chromatin, subfamily-a-like-1) gene. The SMARCAL1 gene encodes for the DNA annealing helicase although it is unknown why this impairment results in skeletal dysplasia, renal dysfunction, and T-cell lymphopenia. The representation of T-cell subsets in SIOD patients is further characterized by a high proportion of memory (CD45RA−CD45RO+)

Abstract:
Mice that lack a functional gamma c subunit of the receptors for interleukin (IL)-2, IL-4, IL-7, IL-9, and IL-15 display profound defects in lymphoid development. The IL-7/IL-7R system represents a critical interaction for conventional T and B cell development. In this report, the role of IL-7R alpha in the development of lymphoid lineages other than conventional T and B cells was examined. We demonstrate that gamma delta + T cells were absent in IL-7R alpha-deficient mice, whereas the development and function of natural killer cells were normal. Thus, IL-7R alpha function is required for the

The high-affinity interleukin 2 receptor (IL-2R) consists of at least three distinct subunits: the IL-2R alpha chain (IL-2R alpha), beta chain (IL-2R beta), and gamma chain (IL-2R gamma). It has been shown that the cytoplasmic region of IL-2R beta, but not of IL-2R alpha, is essential for IL-2 signalling to the cell interior. In the present study, we examined the functional role of the IL-2R gamma cytoplasmic region in the IL-3-dependent mouse hematopoietic cell line BAF-B03, which expresses the endogenous IL-2R alpha and IL-2R gamma, or its subline F7, which additionally expresses human IL-2R

Abstract:
The proinflammatory effects of lipopolysaccharide (LPS) are modulated in large part through the induction of interleukin-1 beta (IL-1 beta) and tumor necrosis factor-alpha (TNF-alpha) release by mononuclear phagocytes. However, IL-1's target cell effects can be suppressed by IL-1 receptor agonist (IL-1ra). Because mononuclear phagocytes produce and respond to IL-1 via IL-1 receptors, we hypothesized that IL-1ra may also be able to block receptors on IL-1 producer cells and inhibit secondary IL-1-induced IL-1 production. To test this hypothesis, mononuclear cells and alveolar macrophages were s

Abstract:
Interleukin-3 (IL-3) stimulates colony formation of multiple lineages of hematopoietic cells. Bone marrow cells of A/J mice are nonresponsive to IL-3, and this observation has recently been correlated with aberrant mRNA splicing and impaired expression of the IL-3 receptor alpha subunit (IL-3R alpha), a binding component of the high-affinity receptors. We examined the IL-3R alpha gene in 27 inbred mouse strains and found the identical mutation, a 5-bp deletion at the branch point of intron 7, in 10 of these mouse strains. Bone marrow cells isolated from these 10 mouse strains did not express I

Interleukin (IL)-7 is an essential non-redundant cytokine and throughout the life-span of a T cell signaling via the IL-7 receptor influences cell survival, proliferation and function. It is therefore no surprise that expression of the IL-7 receptor alpha-chain (CD127) is tightly regulated. In this study I establish IL-7 down regulates CD127 gene transcription and surface protein expression in primary human CD8 T cells through two mechanisms. Upon binding IL-7, surface CD127 is rapidly internalized and phosphorylated at the critical tyrosine residue Y449. Concurrent activation of the JAK/STAT5

Abstract:
Autoimmunity develops over an extended period of time as the result of an amalgamation of genetic, environmental, and immunologic events. Though the precise etiological factors leading to most autoimmune disease are awaiting consensus, a common thread of the autoimmune paradigm is the inappropriate activation of tissue-specific immune cells by one or more autoantigen, which begins the destruction of the tissue. To prohibit immunopathology and fine-tune the immune responses in healthy individuals, the stimulatory activities of effector/memory T (Teffs) cells must be counteracted by the suppress
