[PDF][PDF] Distinct effector B cells induced by unregulated toll-like receptor 7 contribute to pathogenic responses in systemic lupus erythematosus

…, Z Simon, R Bugrovsky, EL Blalock, CD Scharer… - Immunity, 2018 - cell.com
Systemic Lupus Erythematosus (SLE) is characterized by B cells lacking IgD and CD27 (double
negative; DN). We show that DN cell expansions reflected a subset of CXCR5 - CD11c + …

PD-1 combination therapy with IL-2 modifies CD8+ T cell exhaustion program

…, SJ Im, J Lee, JX Lin, B Hu, EE West, CD Scharer… - Nature, 2022 - nature.com
Combination therapy with PD-1 blockade and IL-2 is highly effective during chronic lymphocytic

…, C Desai, TM Darby, L Luo, AA Wolfarth, CD Scharer… - Cell reports, 2015 - cell.com
An optimal gut microbiota influences many beneficial processes in the metazoan host.
However, the molecular mechanisms that mediate and function in symbiont-induced host …

Epigenetic programming underpins B cell dysfunction in human SLE

CD Scharer, EL Blalock, T Mi, BG Barwick… - Nature …, 2019 - nature.com
Systemic lupus erythematosus (SLE) is characterized by the expansion of extrafollicular
pathogenic B cells derived from newly activated naive cells. Although these cells express …

…, P Lu, Y Tang, JW Austin, CD Scharer… - The Journal of …, 2015 - journals.aai.org
Programmed cell death-1 (PD-1) is responsible for T cell exhaustion during chronic viral
infections and is expressed on a variety of immune cells following activation. Despite its …

Plasma cell differentiation is coupled to division-dependent DNA hypomethylation and gene regulation

BG Barwick, CD Scharer, APR Bally, JM Boss - Nature immunology, 2016 - nature.com
The epigenetic processes that regulate antibody-secreting plasma cells are not well understood.
Here, analysis of plasma cell differentiation revealed DNA hypomethylation of 10% of …
