Short Communication: The Immunodeficiency Virus Coreceptor, Bonzo/STRL33/TYMSTR, Is Expressed by Macaque and Human Skin- and Blood-Derived Dendritic Cells
Bibliographic record
Abstract
Dendritic cells (DCs) have been shown to be important in the replication of human and simian immunodeficiency viruses (HIV and SIV, respectively) in vivo and in vitro. DCs express CD4 and several chemokine receptors, such as CCR5 and CXCR4, which are important for viral entry. In vivo, DCs are abundant at body surfaces, where they might be one of the first cells that encounter naturally transmitted virus. Furthermore, DCs pulsed with HIV or SIV in vitro can efficiently transmit virus to T cells, thereby propagating vigorous viral replication. Reports have implicated Bonzo/STRL33/TYMSTR to be an additional alternative coreceptor for HIV and especially SIV infection. However, at present there are no reports regarding the expression of Bonzo/STRL33/TYMSTR by human or macaque DCs. Here we demonstrate the presence of Bonzo/STRL33/TYMSTR transcripts in rhesus macaque and human skin-derived DCs, in immature and mature blood monocyte-derived DCs, and in T cells from both skin and blood. Therefore, Bonzo/STRL33/TYMSTR is expressed in DCs and T cells that can play a role in the transmission of immunodeficiency viruses.

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; both teacher heads agree on what is shown here.
