Germline clone frequency b cell activation
WebNov 20, 2015 · There are approximately 10 10 –10 11 B cells in a human adult [ 28 ]. These cells are critical components of adaptive immunity, and directly bind to pathogens through BCRs expressed on the cell surface. Each B cell expresses a different BCR that allows it to recognize a particular set of molecular patterns. WebColorectal cancer (CRC) is the third most frequently diagnosed malignancy worldwide. Only 5% of all CRC cases are due to germline mutations in known predisposition genes, and the remaining genetic burden still has to be discovered. In this study, we performed whole-exome sequencing on six members of a Polish family diagnosed with CRC and identified …
