Characterization of tubulin genes in Trypanosoma rangeli

Molecular and Biochemical Parasitology
D EsquenaziY M Traub-Cseko


Tubulin genes in Trypanosoma rangeli, the only trypanosome besides T. cruzi to infect humans in America, are organized in homogeneous, alternate alpha and beta gene tandem repeats of 3.8 kb. The basic repeat was cloned, mapped and partially sequenced. In contrast to most other eukaryotes, where tubulin genes are scattered throughout the genome, trypanosomatids so far studied are characterized by tandem arrangements of these genes with the genus Trypanosoma displaying an alternating alpha- and beta-tubulin tandem repeat.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
