T-CellSelectionandFunction

• T-cellselectionrequirestwofeatures:

• Heterodimericcell-surfaceT-cellreceptors

(TCRs:TCRa andTCRb)

• antigenspresentedbyMHC

• Inhealthyindividuals,TCRsarehighlydiverse

• Estimated>1015 possiblecombinations

• “True”diversityisacurrentresearchquestion

T-CellDiversityisCreatedByV(D)JRecombination

• TCRb hasVariable(V),Diversity(D)andJoining(J)genesegments

• TCRa hasVariable(V)andJoining(J)genesegments

• V(D)JreferstocombinedTCRa/b recombination

• TCRb has~50Vx2Dx12Jsegments

=~1,200possiblecombinations(103)

• So…wheredoes1015 diversitycomefrom?

MethodsforImmuneRepertoireProfiling– SingleChain

•Spectratyping–Multiplexsingle-chain(TCRb)PCR–Bands-on-gelvisualization–Lowcostandlowresolution–Verypoorgaugeofdiversity

•RT-PCRandNGS–Usesuniversalsequencesforamplification–Typicallymeasuresexpressionratherthantrueclonality–Single-chain(e.g.TCRb)

•MultiplexPCRandNGS–Flexiblesampletypes,noenrichmentrequired–Canenablequantitativemeasurements–Single-chain(e.g.TCRb)
