Identification of Salp15 Homologues in <i>Ixodes ricinus</i> Ticks
Bibliographic record
Abstract
The 15-kDa Ixodes scapularis salivary gland protein Salp15 protects Borrelia burgdorferi sensu stricto from antibody-mediated killing and facilitates infection of the mammalian host. In addition, Salp 15 has been shown to inhibit T-cell activation. We determined whether Ixodes ricinus, the major vector for Lyme borreliosis in Western Europe, also express salp15-related genes. We show that engorged I. ricinus express salp15 and we have identified three Salp15 homologues within these ticks by reverse transcriptase-polymerase chain reaction (RT-PCR). One of the predicted proteins showed 80% similarity to I. scapularis Salp15, evenly distributed over the entire amino acid sequence, whereas the two other predicted proteins showed approximately 60% similarity, mainly confined to the signal sequence and C-terminus. Comparison of the DNA and protein sequences with those deposited in several databases indicates that these proteins are part of a Salp15 family of which members are conserved among different Ixodes species, all capable of transmitting B. burgdorferi sensu lato. This suggests that these Salp15 homologues could also play a role in the transmission of diverse Borrelia species and in inhibition of T-cell activation.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
