Differential expression of liver fluke β-tubulin isotypes at selected life cycle stages

open access: yes, 2013
We have shown that Fasciola hepatica expresses at least six β-tubulins in the adult stage of its life cycle, designated F.hep-β-tub1–6 (Ryan et al., 2008). Here we show that different complements of tubulin isotypes are expressed in different tissues and

HER2‐Targeted AIE Nanotheranostics Overcome SHR‐A1811 Resistance via Immunogenic Pyroptosis and Tumor‐Associated Macrophage Reprogramming in Breast Cancer

open access: yesSmall, EarlyView.
HER2‐targeted AIE780‐A1811 nanoparticles self‐assemble via amide coupling of a mitochondria‐directed photosensitizer with the ADC SHR‐A1811. Upon 660 nm irradiation, they generate ROS, photothermal effects, and controlled drug release, inducing immunogenic pyroptosis and M2‐to‐M1 macrophage reprogramming. This dual action remodels the immunosuppressive

Detection and Inhalation Hazard Assessment of Wear Particles Arising From Abrasion of Market‐relevant Graphene Reinforced Composites

open access: yesSmall, EarlyView.
Abrasion of few‐layer graphene (FLG)–epoxy composites generated respirable particles in which FLG remained fully embedded, as confirmed by correlative HR‑TEM, Raman, and ToF‑SIMS analyses. Advanced lung cell models revealed no cytotoxic or inflammatory responses, and only high‑dose epoxy particles reduced mucociliary clearance.

Multiple heavy chain isotypes on the membrane of the small B lymphocytes in human blood

open access: yes, 1981
Small lymphocytes from adult human blood were examined for the presence of membrane-associated α, χ, δ and μ Ig isotypes by means of a direct immunofluorescence technique.

Novel Bispecific Engagers Targeting the CεmX Domain of mIgE‐Expressing Cells

open access: yesAllergy, EarlyView.
We developed bispecific TCE & NKCE targeting the CεmX domain of mIgE to eliminate IgE‐producing cells. Both constructs demonstrated potent, specific, dose‐dependent cytotoxicity and selective immune activation in vitro. These results highlight their promise as off‐the‐shelf, potentially curative therapeutics for IgE‐associated allergic diseases ...

Kinetics of Antibody Responses and Effector Cell Sensitivity After High Dose Birch Extract Nasal Challenge

open access: yesAllergy, EarlyView.
High‐dose birch‐extract nasal challenge induced synchronous peaks at 4 weeks in serum specific IgE (sIgE) and basophil sensitivity. Mast cell sensitivity via tSPT and sIgG1 and sIgG4 responses peaked later, at 6–8 weeks. Preseasonal allergen exposure attenuated seasonal sIgE increase and prevented further rise in tSPT sensitivity.

A rare presentation of type 2 hyper IgM syndrome in a 17-year-old male: a case report and literature review

open access: yesAlergologia Polska
Hyper IgM syndrome (HIGM) is a heterogeneous group of primary immunodeficiencies characterized by impaired immunoglobulin class switching, leading to elevated IgM levels and deficiencies in other antibody isotypes.

Dendritic Cell α‐Ketoglutarate Regulates Tfh Polarization in Allergy

open access: yesAllergy, EarlyView.
Allergen induces a dendritic cell metabolism shift toward glutaminolysis with α‐ketoglutarate as a regulator of Tfh subset polarization. Glutaminolysis is required for DC allergen uptake, co‐stimulatory molecule expression, and CLR expression. Modulation of glutaminolysis, JmjD3 histone demethylation, or HIF‐1α degradation alters Tfh polarization and ...

Adaptive Immunity in Marsupials. [PDF]

open access: yesJ Exp Zool A Ecol Integr Physiol
Comparison of the marsupial and eutherian adaptive immune systems. ABSTRACT Marsupials diverged from eutherian mammals 125–160 million years ago. Although evolutionarily distinct, both groups of mammals can produce complex adaptive immune responses to antigens with several key differences.
