Summary: The role of microenvironment-mediated biophysical forces in human lymphomas remains elusive. Diffuse large B cell lymphomas (DLBCLs) are heterogeneous tumors, which originate from highly proliferative germinal center B cells. These tumors, t

The histone methyltransferase EZH2 silences genes by generating H3K27me3 marks. Here the authors use a 3D GC organoid and show EZH2 mediates germinal centre (GC) formation through epigenetic silencing of CDKN1A and release of cell cycle checkpoints.

Nanoparticle shape has emerged as a key regulator of nanoparticle transport across physiological barriers, intracellular uptake, and biodistribution. We report a facile approach to synthesize ellipsoidal nanoparticles through self-assembly of poly(gl

The EZH2 histone methyltransferase is required for B cells to form germinal centers (GC). Here we show that EZH2 mediates GC formation through repression of cyclin-dependent kinase inhibitor CDKN1A (p21Cip1). Deletion of Cdkn1a rescues the GC reactio

Germinal centers are dynamic structures within lymphoid tissues, which develop once B cells receive activating signals from surrounding immune cells. Germinal center B cells are small in number, heterogeneous, and prone to rapid apoptosis unless sele

Induction of B-cell immunity against infection depends on the initiation of the germinal center (GC) reaction in secondary lymphoid organs. Ex vivo recapitulation of the GC reaction in 2D cultures results in transient cell growth, with poor yield and
Most antigen discovery and vaccine development aimed at driving functional B cell responses rely on mouse immunizations studies. To date, there is no 3D ex vivo immune tissues, which are capable of driving antigen-specific B cell responses to rapidly

The development of atherosclerosis involves phenotypic changes among vascular smooth muscle cells (VSMCs) that correlate with stiffening and remodeling of the extracellular matrix (ECM). VSMCs are highly sensitive to the composition and mechanical st

Bioengineered hydrogels have been explored in cell and tissue engineering applications to support cell growth and modulate its behavior. A rationally designed scaffold should allow for encapsulated cells to survive, adhere, proliferate, remodel the n
