TEP1 and infection: Among single or combinations of two Tep mutants, only flies defective at least for Tep4 (ΔTep4 or Tep1, Tep4Δ or TEPqΔ) were less sensitive to the infection than the control or other Tep mutants (Fig. 2A), suggesting that among Drosophila-inducible Teps, only Tep4 loss of function confers an increased survival against S-M. abscessus infection.
