Recent advances in high-throughput sequencing allow for the competitive analysis
of the human B and T cell immune repertoire. In this study we compared
Immunoglobulin and T cell receptor repertoires of lymphocytes found in kidney and
blood samples of 10 patients with various renal diseases based on next-generation
sequencing data. We used Biomed-2 primer panels and ImmunExplorer software to
sequence, analyze and compare complementarity determining regions and V-(D)-J
elements. While generally an individual's renal receptor repertoire is different
from the repertoire present in blood, 94% (30/32) of the lymphocytes with clonal
expansion in kidney can also be traced in blood however, not all of these
clonotypes are equally abundant. Summarizing the data of all analyzed patients,
68% of highly expanded T cell clonotypes and 30% of the highly expanded B cell
clonotypes that have infiltrated the kidney can be found amongst the five most
abundant clonotypes in blood. In addition, complementarity determining region 3
sequences of the immunoglobulin heavy chains are on average more diverse than T
cell receptor beta chains. Immune repertoire analysis of tissue infiltrating B
and T cells adds new approaches to the assessment of adaptive immune response in
kidney diseases. Our data suggest that expanded clonotypes in the tissues might
be traceable in blood samples in the course of treatment or the natural history
of the disease.
