Abstract

Human neutrophil peptide (HNP) defensins were studied to determine their potential effects on adaptive mucosal immunity. Intranasal delivery of HNPs plus ovalbumin (OVA) enhanced OVA-specific serum IgG antibody (Ab) responses. However, OVA-specific IgA Abs were not induced in mucosal secretions or in serum. CD4+T cells of intranasally immunized mice displayed higher OVA-specific proliferative responses and elevated production of interferon γ, interleukin (IL) 5, IL-6, and IL-10 when compared with control groups receiving OVA alone.In vitro, HNPs also enhanced both proliferative responses and T helper (Th) cytokine secretion profiles of CD3ɛ-stimulated spleen- and Peyer’s patch-derived naive CD4+T cells. HNPs modulated the expression of costimulatory molecules by lipopolysaccharide- or CD3ɛ-stimulated splenic and Peyer’s patch B or T cell populations, respectively. These studies show that defensins enhance systemic IgG, but not IgA, Ab responses through help provided by CD4+Th1- and Th2-type cytokines and foster B and T cell interactions to link innate immunity with the adaptive immune system.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
