چکیده

Background: The esebssiwaagoTQ method is applicable for the of study cell gene recombination events as the esebssiwaagoTQ is a measure of the intracellular pressure required to establish a horizontal reading frame for alignment of a gene and its intergene bases for maximal transcription and recombination enzyme activity. B-cell differentiation stages have recently been studied by gene esebssiwaagoTQ-based pressuromodulation mapping. In this study, the B-cell differentiation stage pressuromodulation map is utilized as a template to simulate B-cell immunoglobulin locus recombination events that take place in the pressuromodulated state in vivo. Methods: Chromosome 14 (−) strand location 105,566,277 and 106,879,844 germline genes were recombined after determination of gene esebssiwaagoTQs with respect to the germline, and then recombined genes were recombined further after determination of gene esebssiwaagoTQs with respect to rearranged configurations. For both alleles, first, IGHD_-_ to IGHJ_ was performed, and then IGHV_-_ to IGHD_-_-IGHJ_ was performed. For Allele 1 (IGHM), internal consensus recognition sequence (iCSR) and further CSR isotype switchings were performed; and for Allele 2 (IGHD), homologous recombination was performed and initial allelic exclusion determined. Results: First, the esebssiwaagoTQ of a joining (J_) and diversity (D_-_) gene in its native germline configuration is the basis for predictable subsequent gene rearrangement. Second, D_-_ to J_ gene recombination events are biallelic and mutually exclusive. Third, the entire process from beginning to end depends on the grade of the pressuromodulation effect, and as per the classical pathway it is an antigen presenting cell (APC)-dependent CD4R+ T-cell-mediated B-cell polarization process. Fourth, CD4R+ T-cells are positively pressuromodulated, while B-cells are subject to the effect of both positive and negative forms of antigen pressuromodulation. And fifth, B-cell to plasma cell transformation and the extra-nodal periphery/tissue nidus phase take place in the presence of antigen load and either positive or negative pressuromodulation of the cell to its recombined antibody gene expression intracellular pressure. Conclusions: B-cell gene recombination rearrangement events can be predicted with a reasonable degree of certainty. It is envisioned that further esebssiwaagoTQ-based study of the remaining B-cell variability gene recombinations isotype switching events will further our understanding of pressuromodulated basis for antigen selection including the evolutionary underpinnings of.

Background: The episodic sub-episode block sums split-integrated weighted average-averaged gene overexpression tropy quotient (esebssiwaagoTQ) is a measure of the 5′→ 3′ reading direction intergene distance tropy that needs to be overcome for horizontal alignment of a gene for maximal transcription; and it is also an arbitrary unit measure of the intracellular pressure needed for maximal gene e...

High Resolution Analysis of the Chromatin Landscape of the IgE Switch Region in Human B Cells

Antibodies are assembled by a highly orchestrated series of recombination events during B cell development. One of these events, class switch recombination, is required to produce the IgG, IgE and IgA antibody isotypes characteristic of a secondary immune response. The action of the enzyme activation induced cytidine deaminase is now known to be essential for the initiation of this recombinatio...

Sequential activation and distinct functions for distal and proximal modules within the IgH 3' regulatory region.

As a master regulator of functional Ig heavy chain (IgH) expression, the IgH 3' regulatory region (3'RR) controls multiple transcription events at various stages of B-cell ontogeny, from newly formed B cells until the ultimate plasma cell stage. The IgH 3'RR plays a pivotal role in early B-cell receptor expression, germ-line transcription preceding class switch recombination, interactions betwe...

B cells utilize three DNA alteration strategies-V(D)J recombination, somatic hypermutation (SHM) and class switch recombination (CSR)-to somatically mutate their genome, thereby expressing a plethora of antibodies tailor-made against the innumerable antigens they encounter while in circulation. Of these three events, the single-strand DNA cytidine deaminase, Activation Induced cytidine Deaminas...
