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,

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.

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 ...

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 + ).

Ontogenic restriction of colonization of the bursa of Fabricius
European Journal of Immunology, 1983AbstractThe capacity of hemopoietic precursor cells (HPC) to home to embryonic bursal and thymic grafts was investigated in embryonic and newly hatched chickens. Whereas thymic grafts developed normal histogenesis in both types of recipients, the bursal rudiment was colonized and developed in embryonic, but not in newly hatched hosts.

Secretory cell in the medulla of the bursa of Fabricius
Experientia, 1978Light microscopy has revealed a possible secretory cell in the medulla of the bursa of Fabricius. Cyclophosphamide increased the presence of the secretory cell.

Student and successor of Andreas Vesalius (Fig. 3.1) and Gabriel Fallopius (Fig. 3.2), Girolamo Fabrici or Fabrizio (Fig. 3.3), was professor of Surgery at the University of Padova, Italy, from 1565 to 1613, and practiced and taught Anatomy (Smith et al. 2004). In 1594, he built the first permanent theatre ever designed for public anatomical dissection

Antiserum Specific for Reticulin of the Bursa of Fabricius
International Archives of Allergy and Applied Immunology, 2009Antiserum 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 ...

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 ...

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 ...
