Specific ion channels control sensory gain, sensitivity, and kinetics in a tonic thermonociceptor

Saro, Gabriella ; Lia, Andrei-Stefan ; Thapliyal, Saurabh ; Marques, Filipe ; Busch, Karl Emanuel ; Glauser, Dominique A.

In: Cell Reports, 2020, vol. 30, no. 2, p. 397-408.e4

Pain sensation and aversive behaviors entail the activation of nociceptor neurons, whose function is largely conserved across animals. The functional heterogeneity of nociceptors and ethical concerns are challenges for their study in mammalian models. Here, we investigate the function of a single type of genetically identified C. elegans thermonociceptor named FLP. Using calcium imaging in...

Ubiquitin release from eL40 is required for cytoplasmic maturation and function of 60S ribosomal subunits in Saccharomyces cerevisiae

Martín‐Villanueva, Sara ; Fernández‐Pevida, Antonio ; Fernández‐Fernández, José ; Kressler, Dieter ; Cruz, Jesús de la

In: The FEBS Journal, 2019, vol. 0, no. 0, p. -

Ubiquitin is generated by proteolytic cleavage of precursor proteins in which it is fused either to itself, constituting a linear polyubiquitin protein of head‐to‐tail monomers, or as a single N‐terminal moiety to one of two ribosomal proteins, eL40 (Ubi1/2 precursors) and eS31 (Ubi3 precursor). It has been proposed that the ubiquitin moiety fused to these ribosomal proteins could act...

Adjuvants and the vaccine response to the DS-Cav1-stabilized fusion glycoprotein of respiratory syncytial virus

Sastry, Mallika ; Zhang, Baoshan ; Chen, Man ; Joyce, M. Gordon ; Kong, Wing-Pui ; Chuang, Gwo-Yu ; Ko, Kiyoon ; Kumar, Azad ; Silacci, Chiara ; Thom, Michelle ; Salazar, Andres M. ; Corti, Davide ; Lanzavecchia, Antonio ; Taylor, Geraldine ; Mascola, John R. ; Graham, Barney S. ; Kwong, Peter D.

Appropriate adjuvant selection may be essential to optimize the potency and to tailor the immune response of subunit vaccines. To induce protective responses against respiratory syncytial virus (RSV)—a highly prevalent childhood pathogen without a licensed vaccine—we previously engineered a pre-fusion-stabilized trimeric RSV F (pre-F) “DS-Cav1” immunogen, which induced high titer...
