Transposable elements and their KRAB/KAP1 controllers broadly regulate transcription in adult human cells

Flavia Marzetta

KAP1 is a universal corepressor for the large family of KRAB-ZFP proteins that coordinates epigenetic silencing of endogenous retroelements (EREs) during early embryonic development. This process is essential not just to prevent replication of EREs, but al ...

Modes of antigen presentation by lymph node stromal cells and their immunological implications

Sachiko Hirosue

Antigen presentation is no longer the exclusive domain of cells of hematopoietic origin. Recent works have demonstrated that lymph node stromal cell (LNSC) populations, such as fibroblastic reticular cells, lymphatic and blood endothelial cells, not only p ...

Targeting the tumor-draining lymph node with adjuvanted nanoparticles reshapes the anti-tumor immune response

Jeffrey Alan Hubbell, Melody Swartz, Efthymia Vokali

Accumulating evidence implicates the tumor-draining lymph node (TDLN) in tumor-induced immune escape, as it drains regulatory molecules and leukocytes from the tumor microenvironment. We asked whether targeted delivery of adjuvant to the TDLN, presumably a ...

Tunable T cell immunity towards a protein antigen using polymersomes vs. solid-core nanoparticles

Jeffrey Alan Hubbell, Melody Swartz

Using poly(propylene sulfide) (PPS) and poly(ethylene glycol) (PEG) as components of a nanocarrier platform, we sought to compare immune responses induced by PPS-bl-PEG polymersomes (PSs; watery-core structures, with antigen incorporated within the PSs) an ...

Engineering antigens for in situ erythrocyte binding induces T-cell deletion

Jeffrey Alan Hubbell

Antigens derived from apoptotic cell debris can drive clonal T-cell deletion or anergy, and antigens chemically coupled ex vivo to apoptotic cell surfaces have been shown correspondingly to induce tolerance on infusion. Reasoning that a large number of ery ...

Fluorescent magnetic bead and cell differentiation/counting using a CMOS SPAD matrix

Edoardo Charbon, Martinus Adela Maria Gijs, Caroline Vandevyver, Ulrike Lehmann, Emile Dupont

We present a monolithic silicon chip comprising a matrix of 84 single photon avalanche diodes (SPADs) to detect and discriminate fluorescent beads or fluorescently labeled single cells in a polydimethyl(-siloxane) (PDMS) cartridge that is positioned on top ...

Nanoparticle size influences the magnitude and quality of mucosal immune responses after intranasal immunization

Jeffrey Alan Hubbell, Melody Swartz

Background: The development of nanoparticulate antigen-delivery systems is an important emerging area of vaccinology, being sought to amplify immune responses to recombinant antigens that are poorly immunogenic. Nanoparticle size may play an important role ...

Improving Immunogenicity of Subunit Vaccines Using Nanocarrier Systems

New generation vaccines, which are subunit vaccines, have considerably improved safety profiles, but are often poorly immunogenic, especially when administered through mucosal routes. Also, the diversity of the mechanisms of action of infectious pathogens ...
