Blood B Cell Depletion Reflects Immunosuppression Induced by Live-Attenuated Infectious Bursal Disease Vaccines

Frontiers in Veterinary Science, 2022
Immunosuppression in poultry production is a recurrent problem worldwide, and one of the major viral immunosuppressive agents is Infectious Bursal Disease Virus (IBDV). IBDV infections are mostly controlled by using live-attenuated vaccines.

Host Combats IBDV Infection at Both Protein and RNA Levels

Viruses, 2022
Infectious bursal disease (IBD) is an acute, highly contagious, and immunosuppressive avian disease caused by infectious bursal disease virus (IBDV). In recent years, with the emergence of IBDV variants and recombinant strains, IBDV still threatens the ...

The effects of classic and variant infectious bursal disease viruses on lymphocyte populations in specific-pathogen-free White Leghorn chickens [PDF]

, 2003
Infectious bursal disease virus (IBDV) is a pathogen that primarily infects B lymphocytes in domestic avian species. This viral infection has been associated with immunosuppression, clinical disease/mortality, and enteric malabsorption effects.

Protection of Chickens against Very Virulent Infectious Bursal Disease Virus (IBDV) and Marek's Disease Virus (MDV) with a Recombinant MDV Expressing IBDV VP2 [PDF]

, 1999
To develop a herpes virus vaccine that can induce immunity for an extended period, a recombinant Marek's disease (MD) virus (MDV) CVI-988 strain expressing infectious bursal disease virus (IBDV) host-protective antigen VP2 at theUS2site (rMDV) was ...

PCFT‐Independent Cellular Uptake of Cyclic Cell‐Penetrating Peptide‐Conjugated Folic Acid

ChemBioChem, EarlyView.
Cell‐penetrating peptide (CPP)‐conjugated folic acid mediates efficient internalization of folic acid that is independent of the presence of proton‐coupled folate transporter (PCFT) on the intestinal cells. CPP‐conjugated folic acid demonstrates superior cellular uptake at all studied pH and in the presence of PCFT inhibitors and shows enhanced ...
