The Bursa of Fabricius and Immunoglobulin synthesis
1977Publisher Summary This chapter discusses the Bursa of Fabricius and immunoglobulin synthesis. It emphasizes on bursa morphology, bursa kinetics, and bursa regulation of immunoglobulin production synthesis. Scanning electron microscope and transmission electron microscopy have revealed two distinct types of epithelial cells covering the plicae of the ...

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 ...

Antiserum Specific for Reticulin of the Bursa of Fabricius
International Archives of Allergy and Immunology, 1976Antiserum produced by immunizing rabbits with embryonic chicken spleen cells showed, after appropriate absorption with cell suspensions, specificity for fetal spleen cells in membrane immunofluoresoence tests. However, when the original antiserum was absorbed with tissue homogenates and tested on cryostat tissue sections, it reacted specifically with ...

The Vascularization of the Bursa cloacalis (of Fabricius) in the Duck
Anatomia, Histologia, Embryologia, 1989SummaryThe morphological and structural features of the vascular component of the bursa of Fabricius in the duck are described. By means of an intravasal perfusion of suitably colored neoprene Latex or Microscopaque, or a perfusion of Indian ink, it was possible to follow visually the routes of arteries, veins and the microcirculation; this last ...

Nurse cells of the bursa of Fabricius: Do they exist?
European Journal of Immunology, 1990AbstractCell‐cell interactions in B lymphocyte development have so far been incompletely characterized, mostly due to lack of a special organ for B cell maturation in the mammalian species. Certain well‐known lymphostromal interactions in the thymus have raised the question whether similar interactions with nurse cells would also operate in the ...

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 ...

Cryptosporidiosis of the bursa of fabricius and trachea in broilers
Avian Pathology, 1982Cryptosporidial parasitisation of the bursa of Fabricius and trachea is described in broilers. The response in both tissues was of epithelial hyperplasia and inflammatory cell infiltration. No clinical signs were reported.

The Influence of Desoxycorticosteron on the Thymus and Bursa of Fabricius in the Chicken
Zentralblatt für Veterinärmedizin Reihe A, 1979SummaryStudler‐Cornish, tetralinear hybrid chickens, aged 14 days, were injected intrapectorally with 1, 3.5 and 5. mg./100 g. body weight DOCA. After 3 days a constant increase of thymus and bursa weight and RNA content was found, while the quantity of glycogen decreased.The quantity of DNA and total proteins showed variable or insignificant changes ...

In vitro organ culture of embryonic bursa of fabricius
Developmental & Comparative Immunology, 1990An in vitro method for organ culture of embryonic bursa of Fabricius is presented. It is shown that bursa cells proliferate in in vitro culture as evidenced by [3H]-thymidine incorporation. We assessed the expression of B-cell alloantigen (Bu-la and Bu-lb), class I (B-F) and class II (B-L) antigens of chicken major histocompatibility complex (MHC), and

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 (
