Niche-Mediated Integrin Signaling Supports Steady-State Hematopoiesis in the Spleen

Outside-in integrin signaling regulates cell fate decisions in a variety of cell types, including hematopoietic stem cells (HSCs). Our earlier published studies showed that interruption of periostin (POSTN) and integrin-av (ITGAV) interaction induces faste ...

Blood Flow to the Spleen is Altered in a Mouse Model of Spinal Muscular Atrophy

Bernard Schneider

Spinal muscular atrophy (SMA) is a neuromuscular disorder affecting young children. While pre-clinical models of SMA show small spleens, the same is not true in humans. Here, we show by doppler ultrasonography decreased splenic blood flow in Smn(2B/-) mice ...

PPS nanoparticles as versatile delivery system to induce systemic and broad mucosal immunity after intranasal administration

Eleonora Simeoni, Jeffrey Alan Hubbell, Melody Swartz, Mikaël Martino, Armando Stano

Degradable polymer nanoparticles (NPs, 50nm) based on polypropylene sulfide (PPS) were conjugated to thiolated antigen and adjuvant proteins by reversible disulfide bonds and evaluated in mucosal vaccination. Ovalbumin was used as a model antigen, and anti ...

Analysis Of Failure Mechanisms In Platelet-Reinforced Composites

Yves Leterrier

The short-term mechanical strength of platelet-reinforced polymer composites was modeled using classical two-dimensional stress-transfer analysis. The stress field in the platelet and at the platelet/matrix interface was described in the presence of a matr ...

Role of Interferon-Gamma in Interleukin 12-Induced Pathology in Mice

Michel Aguet

Interleukin 12 (IL-12) activates natural killer (NK) and T cells with the secondary synthesis and release of interferon-gamma (IFN-gamma) and other cytokines. IL-12-induced organ alterations are reported for mice and the pathogenetic role of IFN-gamma is i ...

Mice from a genetically resistant background lacking the interferon gamma receptor are susceptible to infection with Leishmania major but mount a polarized T helper cell 1-type CD4+ T cell response

Michel Aguet

Mice with homologous disruption of the gene coding for the ligand-binding chain of the interferon (IFN) gamma receptor and derived from a strain genetically resistant to infection with Leishmania major have been used to study further the role of this cytok ...

Interferon gamma receptor deficient mice are resistant to endotoxic shock

Michel Aguet

Antibody neutralization studies have established interferon gamma (IFN-gamma) as a critical mediator of endotoxic shock. The advent of IFN-gamma receptor negative (IFN gamma R-/-) mutant mice has enabled a more direct assessment of the role of IFN-gamma in ...

Post-transcriptional regulation of the transferrin receptor and 4F2 antigen heavy chain mRNA during growth activation of spleen cells

Lukas Kühn

The expression of several cell surface proteins including the transferrin receptor and 4F2 antigen is induced when quiescent cells are activated and proliferate. We have studied this induction in mouse spleen cells after stimulation with 4 beta-phorbol 12- ...

A monoclonal antibody against altered LFA-1 induces proliferation and lymphokine release of cloned T cells

Michel Aguet

A murine monoclonal antibody (I-17, IgM) has the following functional effects on murine long-term T cell clones: inhibition of cell-mediated lysis, induction of proliferation, release of lymphokines and change of the cell morphology. The determinant detect ...
