  We argue that brane anti-brane inflation in string theory de-Sitter vacua of
Kachru-Kallosh-Linde-Trivedi (KKLT) is captured by the dynamics of a D3-brane
probe in the local KKLT model constructed in hep-th/0203041. This provides a
framework to study in a controllable way corrections to the inflationary slow
roll parameter \eta due to conformal symmetry breaking in a warped geometry
throat. We compute the leading correction to \eta for the inflation in the
Klebanov-Tseytlin throat geometry. We find that in certain regime this
correction tends to decrease \eta. Computations in a different regime suggest
however that it is unlikely that \eta << 1 can be achieved with the D3-brane
throat inflation.
