Histone fractions in chicken bursa of fabricius and thymus
Comparative Biochemistry and Physiology Part A: Physiology, 1973Abstract 1. 1. Whole histone and the five main histone fractions were isolated from chicken bursa of Fabricius and thymus. 2. 2. The proteins were all characterized by polyacrylamide gel electrophoresis and amino acid analyses and compared with the corresponding fractions from calf thymus. 3. 3.

Early Changes in Bursa of Fabricius from Marek's Disease
Avian Diseases, 1969SUMMARY Seventy Line 7 X specific-pathogen-free (SPF) hybrids were inoculated with four isolates of the Marek's disease (MD) agent. The strains used were the JM and Conn-A agents, chosen as standard isolates, and materials from two field outbreaks. Whole blood from infected donors was the source of inoculum; both undiluted and phosphate-buffered saline

Shared Antigenicity between Chicken Brain and Bursa of Fabricius
International Archives of Allergy and Immunology, 1975Antisera to chicken brain, thymus and bursa of Fabricius were prepared in rabbits and rendered organ-specific by appropriate absorptions. Brain was shown by immunofluorescence and immune adherence to have common antigenicity with the bursa of Fabricius but not with the thymus.

Studies of testosterone-induced involution of the bursa of Fabricius
Developmental Biology, 1980Abstract The present investigation deals with the effect of testosterone on each of the tissue components of the bursa of Fabricius: the endodermal epithelium, the mesenchyme, and the hemopoietic stem cells. Tissue combination experiments between testosterone-treated endoderm and normal mesenchyme and vice versa have shown that the androgen damages ...

Demonstration of Eimeria tenella in Bursa of Fabricius of Chickens
Avian Diseases, 1976Coccidial life-cytle stages were detected in the bursa of Fabricius of broiler chickens inoculated with Eimeria tenella, whether or not the chickens had previously been infected with infectious bursal disease virus (IBDV). Chickens infected only with E. tenella had developing parasites in the lining epithelium, whereas chickens with both infections had

Emigration of B cells from chicken bursa of Fabricius
European Journal of Immunology, 1989AbstractThe extent of emigration of cells from the bursa of Fabricius to the periphery was estimated. Per anum application of fluorescein isothiocyanate to label bursal cells in situ was used. Migrant cells can be visualized on frozen sections or cell suspensions of peripheral organs by their fluorescence. The data show that at 2–3 weeks after hatching

Sex steroid sensitivity of developing bursa of Fabricius.
The International Journal of Developmental Biology, 1989Sex steroid sensitivity of the bursa of Fabricius (BF) was studied from the early embryonic time until its regression. Expression of progesterone receptor (PR) served as a dual marker: first, as a marker for progesterone sensitivity and second, as a marker for estrogen action, since it is an estrogen-induced protein.

The Bursa of Fabricius: A Central Issue
BioScience, 1970Prior to 1955-56, the function of the avian and mammalian thymus and avian bursa of Fabricius was still an enigma. At this time, we revealed that removal of the bursa would reduce or eliminate future antibody production (Glick et al., 1956). Other investigators confirmed and extended this work to include that the mammalian and avian thymus control ...

Apoptotic Cell Death in the Chicken Bursa of Fabricius
1996The bursa of Fabricius is the site of primary B cell development in birds, and has been reviewed extensively elsewhere1–3. It is productively colonized during embryonic life by a small number (
