B-cell clusters participating in oligoclonal band (OCB) production undergo immune stimulation in the periphery. (A) Lineage tree (organic layout) and (B) alignment of representative immunoglobulin G (Ig) heavy chain variable region (IgG-VH) amino acid sequences from Patient MS-5 are shown. Germline node (black arrow), node comprised of cerebrospinal fluid (CSF) and peripheral blood (PB) mononuclear cell (PBMC) IgG-VH (green arrow), and PB-derived subcluster identified by OCB peptide searches (gray arrow) are indicated. In the alignment, matched OCB peptides are shaded in gray; IgG-VH is derived from the Ig heavy chain variable germline gene (IGHV)3–9 germline segment. Only representative IgG-VHs are shown. Organic layout was chosen over hierarchic layout because the latter generates very extensive horizontal images. For additional information, please refer to the legends of Figures 1 and 2.
