Titrating T-cell epitopes within self-assembled vaccines optimizes CD4+ helper T cell and antibody outputs.

Rebecca R Pompano et al.

Advanced healthcare materials, 3(11), 1898-1908 (2014-06-14)

Epitope content plays a critical role in determining T-cell and antibody responses to vaccines, biomaterials, and protein therapeutics, but its effects are nonlinear and difficult to isolate. Here, molecular self-assembly is used to build a vaccine with precise control over

Shp1 signalling is required to establish the long-lived bone marrow plasma cell pool.

Yan-Feng Li et al.

Nature communications, 5, 4273-4273 (2014-07-01)

Germline or B-cell-specific loss of Ptpn6 gene encoding the Shp1 protein tyrosine phosphatase leads to skewed B lymphopoiesis and systemic autoimmunity. Here, to study its role in B-cell terminal differentiation, we generated Ptpn6(f/f)Aicda(Cre/+) mice with Shp1 ablated only in activated

Immunity induced by a broad class of inorganic crystalline materials is directly controlled by their chemistry.

Gareth R Williams et al.

The Journal of experimental medicine, 211(6), 1019-1025 (2014-05-07)

There is currently no paradigm in immunology that enables an accurate prediction of how the immune system will respond to any given agent. Here we show that the immunological responses induced by members of a broad class of inorganic crystalline

Dendritic cell-bound IgE functions to restrain allergic inflammation at mucosal sites.

B Platzer et al.

Mucosal immunology, 8(3), 516-532 (2014-09-18)

Antigen-mediated cross-linking of Immunoglobulin E (IgE) bound to mast cells/basophils via FcɛRI, the high affinity IgE Fc-receptor, is a well-known trigger of allergy. In humans, but not mice, dendritic cells (DCs) also express FcɛRI that is constitutively occupied with IgE.

Nasal allergen deposition leads to conjunctival mast cell degranulation in allergic rhinoconjunctivitis.

Ina Callebaut et al.

American journal of rhinology & allergy, 28(4), 290-296 (2014-09-10)

The naso-ocular interaction in allergic rhinoconjunctivitis is well recognized from epidemiological, clinical, and experimental observations. The precise mechanisms remain incompletely understood. A new mouse model of allergic rhinoconjunctivitis was used to investigate the contribution of mast cells and trigeminal ganglia
