Evaluation of the Effects of Colostrum Substitutes on IgG Levels and Humoral Immune Development in Polypay Lambs [PDF]

open access: yesVeterinary Sciences
This study investigated colostrum source impact on passive immunity transfer and humoral immune development in Polypay lambs. Newborn lambs (4.80 ± 0.33 kg BW) were assigned to four groups: fresh ewe colostrum (FrC; n = 10), frozen ewe colostrum (FZ; n =

Therapeutic effects of a combination of Chinese quince and Saururus chinensis extract on allergic airway inflammation in an ovalbumin-induced asthma mouse model [PDF]

open access: yesFrontiers in Nutrition
BackgroundAllergic asthma involves chronic inflammation, airway remodeling, and hyperresponsiveness. Inhaled corticosteroids combined with long-acting β2 agonists are effective; however, some patients experience side effects, highlighting the need for ...

Oral tolerance induction with altered forms of ovalbumin [PDF]

open access: goldBrazilian Journal of Medical and Biological Research, 1998
As a T cell-dependent phenomenon, oral tolerance is not expected to depend necessarily on native configuration of antigens. We investigated the induction of oral tolerance with modified ovalbumin (Ova).

Electroporation-based Easi-CRISPR yields biallelic insertions of EGFP-HiBiT cassette in immortalized chicken oviduct epithelial cells

open access: yesPoultry Science, 2023
: Laying hens are an excellent experimental oviduct model for studying reproduction biology. Because chicken oviduct epithelial cells (cOECs) have a crucial role in synthesizing and secreting ovalbumin, laying hens have been regarded an ideal bioreactor ...

Simple Nanoparticles from the Assembly of Cationic Polymer and Antigen as Immunoadjuvants

open access: yesVaccines, 2020
Since antigens are negatively charged, they combine well with positively charged adjuvants. Here, ovalbumin (OVA) (0.1 mg·mL−1) and poly (diallyldimethylammonium chloride) (PDDA) (0.01 mg·mL−1) yielded PDDA/OVA assemblies ...
