Ephrin Receptor Expression in the Embryonic Bursa of Fabricius
Utilizing degenerate PCR primers complementary to conserved regions within the kinase domain of Receptor Tyrosine Kinase (RTK) genes, the goal was to compare the full complement of RTK expressed (mRNA level) between two developmental stages of bursal B-cells. We identified 21 different RTK cDNAs out of a total of 235 cDNAs sequenced between the two B-cell stages. The dataset revealed the expres...
متن کاملRearrangement of chicken immunoglobulin genes is not an ongoing process in the embryonic bursa of Fabricius.
We report a molecular analysis of the chicken Ig loci in single bursal follicles from 3- to 7-week-old chickens. Each follicle contained between 10(5) and 3 X 10(5) cells. The Ig gene rearrangement patterns obtained were compared to the pattern observed with the corresponding total bursal DNA. The results obtained for the light chain locus imply that a very small number (two on average) of rear...
متن کاملThe structure of the bursa of Fabricius in wild birds.
B. Glick et all,2 found that the antibody-producing ability is markedly re duced when the bursa of Fabricius (abbreviated as BF) of the newly-hatched chick is removed. Thus the function of this organ which is specific for birds received a great deal of attention. With the comparative study of bursectomy and thymectomy, it has been ascertained that the BF and the thymus play distinctive roles in...
متن کاملThe Thymus and the Bursa of Fabricius in Chickens
The effect of cyclephosphamide (Cy) on the thymus and the bursa of Fabricius in chickens, aged one day to 7 weeks, was examined morphologically, Chiekens, which were daily injected i.m. with 6mg Cy 1, 2, or 3 times from the hatching day, were compared with saline coutrel chickens, The relative weights of both the thymus and the bursa decreased abruptly just after the injection of Cy. The weight...
متن کاملAnalysis of gene expression during myc oncogene-induced lymphomagenesis in the bursa of Fabricius.
The transcriptional effects of deregulated myc gene overexpression are implicated in tumorigenesis in a spectrum of experimental and naturally occurring neoplasms. In follicles of the chicken bursa of Fabricius, myc induction of B-cell neoplasia requires a target cell population present during early bursal development and progresses through preneoplastic transformed follicles to metastatic lymp...
