Phagocytosis of apoptotic cells by macrophages from NOD mice is reduced

- diabetesjournals.org
BA O'Brien, Y Huang, X Geng, JP Dutz, DT … - Diabetes, 2002 - Am Diabetes Assoc
Macrophages limit inflammatory responses by clearing apoptotic cells.
Deficiencies in apoptotic cell phagocytosis have been linked to autoimmunity. In
this study, we determined the efficiency with which macrophages from ...

Clearance of apoptotic beta-cells is reduced in neonatal autoimmune diabetes-prone rats.


BA O'Brien, WE Fieldus, CJ Field, DT … - Cell death and differentiation, 2002 - ncbi.nlm.nih.gov
The kinetics of beta-cell death in neonatal diabetes-prone (BBdp) and
diabetes-resistant (BBdr) BioBreeding rats was investigated using both direct
(histochemical) and indirect (mathematical modelling) techniques. In both ...

Neonatal beta-cell apoptosis: a trigger for autoimmune diabetes?

- diabetesjournals.org [PDF] 
JD Trudeau, JP Dutz, E Arany, DJ Hill, WE … - Diabetes, 2000 - Am Diabetes Assoc
In neonatal rodents, the -cell mass undergoes a phase of remodeling that
includes a wave of apoptosis. Using both mathematical modeling and histochemical
detec- tion methods, we have demonstrated that -cell apo- ptosis is ...

Abnormalities in dendritic cell and macrophage accumulation in the pancreas of nonobese …


S Charre, JG Rosmalen, C Pelegri, V Alves, … - Histology and histopathology, 2002 - ncbi.nlm.nih.gov
Dendritic cell (DC), macrophage (Mphi) and lymphocyte infiltrations have been
observed in normal human perinatal pancreata, but have never been investigated
so early in control mice. In type 1 diabetes-prone NOD mice, these cells ...

Quantifying macrophage defects in type 1 diabetes

- ubc.ca [PDF] 
AFM Marée, M Komba, C Dyck, M Łabęcki, DT … - Journal of theoretical biology, 2005 - Elsevier
Macrophages from animals prone to autoimmune (type 1) diabetes differ from those
of diabetes-resistant animals in processing and clearing apoptotic cells. Using
in vitro time-course assays of the number of engulfed apoptotic cells ...

NOD macrophages produce high levels of inflammatory cytokines upon encounter of apoptotic …


K Stoffels, L Overbergh, A Giulietti, A Kasran … - Journal of Autoimmunity, 2004 - Elsevier
During the development of type 1 diabetes, pancreatic beta-cells are subject to
an immune attack, leading to their apoptotic or necrotic cell death. Apoptotic
beta-cells are also present during periods of tissue remodeling, such as in ...

A deficiency in the in vivo clearance of apoptotic cells is a feature of the NOD mouse


BA O'Brien, X Geng, CH Orteu, Y Huang, M … - Journal of Autoimmunity, 2006 - Elsevier
Deficiencies in apoptotic cell clearance have been linked to autoimmunity. Here
we examined the time-course of peritoneal macrophage phagocytosis of dying cells
following the direct injection of apoptotic thymocytes into the peritoneum ...

Tolerance to islet antigens and prevention from diabetes induced by limited apoptosis of …

- cell.com
S Hugues, E Mougneau, W Ferlin, D Jeske, P … - Immunity, 2002 - Elsevier
Crosspresentation of self-antigens by antigen-presenting cells is critical for
the induction of peripheral tolerance. As apoptosis facilitates the entry of
antigens into the crosspresentation pathway, we sought to prevent the ...

AFM Marée, R Kublik, DT Finegood, L … - Philosophical Transactions of the Royal Society A: …, 2006 - rsta.royalsocietypublishing.org
A wave of apoptosis (programmed cell death) occurs normally in pancreatic
β-cells of newborn mice. We previously showed that macrophages from non-obese
diabetic (NOD) mice become activated more slowly and engulf apoptotic cells ...

Splenic macrophages from the NOD mouse are defective in the ability to present antigen


JD Piganelli, T Martin, K Haskins - Diabetes-American Diabetes Association, 1998 - Am Diabetes Assoc
IDDM results from the destruction of pancreatic -cells by autoreactive T-cells
that appear to avoid deletion early in development, possibly due to improper
interac- tion with antigen-presenting cells (APCs) resident in the thymus ...
