A Study Of The Genetic Mechanisms Used To Regulate The Third Complementarity Determining Region Of The Immunoglobulin H Chain, Mohamed Khass

All ETDs from UAB

Developing B cells exhibit sequential changes in the representation of immunoglobulin (Ig) heavy (H) chain sequences with excess hydrophobic or charged amino acids in complementarity determining region 3 (CDR-H3). To begin to elucidate the mechanisms by which this process occurs, we used Bromodeoxy Uridine (BrdU) incorporation and Annexin V binding to quantify B cell turnover and cell cycle progression in developing B cell subsets in the bone marrow, spleen and peritoneal cavity of wild-type BALB/c mice. To magnify the effects of hydrophobicity and charge, we included in this analysis mice limited to the use of an IgH allele with a …
