Finally, we provide evidence that the binding of BSAP prevents USF and B-MEF2 from interacting with the J chain promoter during the antigen-independent stages of B cell development. It is not until the levels of BSAP decrease during the antigen-driven stages of B cell development that both ...
We previously demonstrated that an Sp1-dependent reporter gene is preferentially expressed in G2 of the 1-cell mouse embryo following microinjection of the... DM Worrad,PT Ram,RM Schultz - 《Development》 被引量: 410发表: 1994年 Characterization of early stages of human B cell development by...
Finally, ASC can be further subseted based on their differential responses to ER-stress, indicating multiple development branch points. Our data thus define the cell division kinetics of B cell differentiation in vivo, and identify the molecular trajectories of B cell fate and ASC formation....

During the past year, there have been rapid advances in our understanding of the early events of T-cell development, at the molecular level. Studies at the transcriptional level of T-cell receptor gene regulation have started to yield important clues about how different T-cell-specific genes can...
However, molecular regulatory mecha- nisms of A. suturalis largely remained unexplored due to the general lack of genomic resources especially relating to major transitional stages of its life cycle, which are needed to better enable the development of alternative control and management strategies of ...
This response could be modified by manipulation of the endocrine environment during early stages in rat development. To further examine the influence of changing hormonal steroid milieu and vitamin D status on the action of gonadal steroids in developing bone tissue, we used two models of ectopic ...
Preceding chapters have mainly described various methods for sampling the different developmental stages and age groups of Mosquito populations. This chapter is concerned with analysing the numerical changes that occur in population size during the life-
