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 ...

Lymphocyte-Differentiating Hormone of Bursa of Fabricius
Science, 1976Induction of early lymphocyte differentiation was studied in vitro in fractionated bone marrow cells of newly hatched chickens, with alloantiserums to identify newly differentiated B cells (Bu-1 + ) and T cells (Th-1 + ).

Uptake of environmental antigens by the bursa of Fabricius
Nature, 1975THE bursa of Fabricius of birds has an essential role as a central lymphoid organ for the differentiation of B lymphocytes1,2. In addition, the bursa harbours immunocompetent B cells3 which are capable of local antibody production. Haemolytic plaque-forming cells have been observed in the bursa after introducing sheep red blood cells (SRBC) into the ...

On the development of the lymphoid follicles of the bursa of fabricius
The Anatomical Record, 1975AbstractThe structural features of the development of the bursa of Fabricius in white Leghom chick embryos are depicted at carefully timed intervals during embryogenesis, with emphasis on the sequence of events between the ninth and twelfth days of incubation.

Experimental studies on the development of the bursa of Fabricius
Developmental Biology, 1966Abstract An analysis of the origin of lymphoid cells in the developing bursa of Fabricius has been made using a chromosome marker technique in combination with various experimental procedures including parabiosis of embryos of similar major histocompatibility type, twin embryo studies, transplantation of bursal rudiments to the chorioallantois, and ...

Follicular exclusion of retroviruses in the bursa of fabricius
Virology, 1989To gain insight into the regulation of retroviral infection at the cellular level, we analyzed the distribution of retroviral antigen and nucleic acid in the bursa of Fabricius of the parents and progeny of two highly inbred lines of chickens, one resistant and the other susceptible to infection. Line 15I5 chickens and line 7(2), which are C/C and C/A,

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 ...

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 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 ...
