New Identification Tools for the Nymphs of Three Amblyomma spp. Koch (Ixodida: Ixodidae) in South Texas.

Taxonomic uncertainties and morphologic and molecular similarities may lead to incorrect or incomplete species identifications of immature ticks. This problem can be compounded when the diagnostic morphological features used are unreliable, unstable, or difficult to view. Our study attempts to sort out the similar morphologies of three Amblyomma spp.

Single-cell transcriptomics identifies potential cells of origin of MYC rhabdoid tumors.

Rhabdoid tumors (RT) are rare and highly aggressive pediatric neoplasms. Their epigenetically-driven intertumoral heterogeneity is well described; however, the cellular origin of RT remains an enigma. Here, we establish and characterize different genetically engineered mouse models driven under the control of distinct promoters and being active in early progenitor cell types with diverse embryonic onsets.

Rhipicephalus capensis (Acari: Ixodidae), A geographically restricted South African tick, returning with a human traveler to the United States.

Accelerated frequency of recreational travel, globalization of business, and legal and illegal plant and animal trades have contributed to enduring introductions of exotic ticks into the United States. We herein report a new incursion of a female Rhipicephalus capensis on a human traveler returning to Connecticut from South Africa. Natural distribution of R.

The mesoscale organization of syntaxin 1A and SNAP25 is determined by SNARE-SNARE interactions.

SNARE proteins have been described as the effectors of fusion events in the secretory pathway more than two decades ago. The strong interactions between SNARE domains are clearly important in membrane fusion, but it is unclear whether they are involved in any other cellular processes. Here, we analyzed two classical SNARE proteins, syntaxin 1A and SNAP25.
