A critical role for Syk in signal transduction and phagocytosis mediated by Fcγ receptors on macrophages

…, C Lowell, VLJ Tybulewicz, AL DeFranco - Journal of Experimental …, 1997 - rupress.org
Receptors on macrophages for the Fc region of IgG (Fc R) mediate a number of responses
important for host immunity. Signaling events necessary for these responses are likely …

Activation of c-Jun N-terminal kinase in bacterial lipopolysaccharide-stimulated macrophages.

…, SL Weinstein, L Lem, AL DeFranco - Proceedings of the …, 1996 - pnas.org
Activation of macrophages by bacterial lipopolysaccharide (LPS) induces transcription of
genes that encode for proinflammatory regulators of the immune response. Previous work has …

Characterization of the B lymphocyte populations in Lyn-deficient mice and the role of Lyn in signal initiation and down-regulation

VWF Chan, F Meng, P Soriano, AL DeFranco… - Immunity, 1997 - cell.com
Lyn-deficient mice were generated to analyze the role of Lyn in B cell antigen receptor (BCR)
signaling. These mice had a reduced number of peripheral B cells with a greater …

Nephropathy requiring dialysis after percutaneous coronary intervention and the critical role of an adjusted contrast dose

…, E Kline-Rogers, VL Clark, AC DeFranco… - The American journal of …, 2002 - Elsevier
This study was undertaken to determine the incidence, risk factors, and in-hospital outcome
of nephropathy requiring dialysis (NRD) after percutaneous coronary intervention (PCI), and …

Toll-like receptors activate innate and adaptive immunity by using dendritic cell-intrinsic and-extrinsic mechanisms

B Hou, B Reizis, AL DeFranco - Immunity, 2008 - cell.com
Toll-like receptors (TLRs) play prominent roles in initiating immune responses to infection, but
their roles in particular cell types in vivo are not established. Here we report the generation …

γδ intraepithelial lymphocytes are essential mediators of host–microbial homeostasis at the intestinal mucosal surface

…, JL Benjamin, KA Ruhn, B Hou, AL DeFranco… - Proceedings of the …, 2011 - pnas.org
The mammalian gastrointestinal tract harbors thousands of bacterial species that include
symbionts as well as potential pathogens. The immune responses that limit access of these …

Fcγ receptor–mediated phagocytosis in macrophages lacking the Src family tyrosine kinases Hck, Fgr, and Lyn

…, MT Crowley, AJ Finn, F Meng, AL DeFranco… - The Journal of …, 2000 - rupress.org
Macrophage Fcγ receptors (FcγRs) mediate the uptake and destruction of antibody-coated
viruses, bacteria, and parasites. We examined FcγR signaling and phagocytic function in …

The complexity of signaling pathways activated by the BCR

AL DeFranco - Current opinion in immunology, 1997 - Elsevier
Cross-linking of the B cell antigen receptor (BCR) leads to the activation of three types of
intracellular protein tyrosine kinases. These tyrosine kinases then phosphorylate signaling …

Ligand-regulated chimeric receptor approach reveals distinctive subcellular localization and signaling properties of the Toll-like receptors

T Nishiya, AL DeFranco - Journal of Biological Chemistry, 2004 - jbc.org
Toll-like receptors (TLRs) are sensors for the detection of invading infectious agents and
can initiate innate immune responses. Because the innate immune system induces an …

Selective utilization of Toll-like receptor and MyD88 signaling in B cells for enhancement of the antiviral germinal center response

…, LM Lee, RL Coffman, MF Bachmann, AL DeFranco - Immunity, 2011 - cell.com
The contribution of Toll-like receptor (TLR) signaling to T cell-dependent (TD) antibody
responses was assessed by using mice lacking the TLR signaling adaptor MyD88 in individual …
