How Epstein-Barr virus envelope glycoprotein gp350 tricks the CR2? A molecular dynamics study.

J Mol Graph Model 2022 Jul 26;114:108196. Epub 2022 Apr 26.

Department of Bioengineering, Faculty of Engineering, Marmara University, Istanbul, Turkey. Electronic address:

The connection of Epstein Barr virus (EBV) with diseases such as Burkitt Lymphoma, Hodgkin disease, multiple sclerosis, systemic lupus erythematosus and various B-cell lymphomas made EBV glycoproteins one of the most popular vaccine immunogens. As a protein being encoded by EBV, the viral membrane envelope protein gp350 is studied extensively due to its abundancy on the surface and its interaction with complementary receptor, CR2. The binding of CR2 and gp350 not only leads to the entrance of the virus to the B-cells, but also prevents CR2 and C3d protein interactions that are required for immune response. Read More

Autoimmune Cytopenia in CLL: Prognosis and Management in the Era of Targeted Therapies.

Cancer J 2021 Jul-Aug 01;27(4):286-296

From the Department of Hematology, Hospital de la Santa Creu i Sant Pau, Autonomous University of Barcelona, Barcelona, Spain.

Abstract: Chronic lymphocytic leukemia (CLL) is frequently associated with autoimmune hemolytic anemia and immune thrombocytopenia and, less frequently, with pure red cell aplasia and immune neutropenia. The emergence of these complications is related to an intertwined and complex relationship between patient, disease, and treatment characteristics. The prognostic repercussion of autoimmune cytopenia (AIC) in patients with CLL mainly depends on its response to therapy. Read More

Traceless aptamer-mediated isolation of CD8 T cells for chimeric antigen receptor T-cell therapy.

Nat Biomed Eng 2019 10 17;3(10):783-795. Epub 2019 Jun 17.

Department of Bioengineering, University of Washington, Seattle, WA, USA.

Chimeric antigen receptor T-cell therapies using defined product compositions require high-purity T-cell isolation systems that, unlike immunomagnetic positive enrichment, are inexpensive and leave no trace on the final cell product. Here, we show that DNA aptamers (generated with a modified cell-SELEX procedure to display low-nanomolar affinity for the T-cell marker CD8) enable the traceless isolation of pure CD8 T cells at low cost and high yield. Captured CD8 T cells are released label-free by complementary oligonucleotides that undergo toehold-mediated strand displacement with the aptamer. Read More

B cell responses to apoptotic cells in MFG-E8-/- mice.

Authors:
YuFeng Peng

PLoS One 2018 4;13(10):e0205172. Epub 2018 Oct 4.

Division of Rheumatology, Department of Medicine, University of Washington, Seattle, Washington, United States of America.

Defective clearance of apoptotic cells in MFG-E8 deficient mice results in lupus-like disease in the mixed B6x129, but not pure B6 background. The lack of overt autoimmunity in MFG-E8-/- B6 mice suggests that accumulation of apoptotic cells is not sufficient to break central tolerance. However, the delayed clearance of apoptotic cells in the follicles of MFG-E8-/- B6 mice provides an excellent opportunity to investigate how B cells respond to excessive apoptotic cells in the periphery under relatively non-inflammatory conditions.
