To study the nature of persistent polyclonal B cell lymphocytosis (PPBL), we purified CD27posIgMposIgDpos from 4 patients, as well as transitional (CD38hiCD24hi), pre-naive (CD38dimCD24dimCD5pos), naive mature (CD38dimCD24dimCD5-CD27-), natural effector (CD27posIgMposIgDpos) and IgM-only (CD27posIgM...

Advanced analytical strategies including top-down and middle-up HPLC-MS approaches have become powerful alternatives to classical bottom-up analysis for the characterization of therapeutic monoclonal antibodies. Here, we assess feasibility of middle-up analysis of polyclonal IgGs posing additional c...

Polyclonal interactions overcome fitness barriers in Apc-driven intestinal tumorigenesis
Antigen-antibody interactions play a key role in the immune response post vaccination and the mechanism of action of antibody-based biopharmaceuticals. 4CMenB is a multicomponent vaccine against Neisseria meningitidis serogroup B in which factor H binding protein (fHbp) is one of the key antigens. I...

ThymoSpheres culture: a model to study human polyclonal unconventional T cells
ZBTB20 is an adjuvant-specific factor for long-term antibody responses. This factor is critical for maintaining long-lived plasma cells in alum-adjuvanted antibody responses but is dispensable for TLR ligand-adjuvanted responses. To identify the functions of ZBTB20 in long-lived plasma cells, we per...

The pathogenesis of glaucoma is strongly associated with the occurrence of autoimmune-mediated loss of retinal ganglion cells (RGCs) and recently it was proven that specific antibody-derived signature peptides are significantly differentially expressed in sera of primary open angle glaucoma patients...

γδ-T lymphocytes are cells of the innate immune system exerting potent natural cytotoxicity against bacteria, viruses and tumours. This ability, coupled with their negligible alloreactivity, makes them attractive for adoptive immunotherapy approaches. To achieve a cell product suitable for clinical ...

Middle-up strategy for the analysis of the fragment crystallizable (Fc) region of human plasma immunoglobulins G (IgGs). The use of hydrophilic interaction liquid chromatography (HILIC) and capillary electrophoresis (CE) coupled to mass spectrometry (MS) allowed to get a comprenhesive view of the N-...
