Rabies remains an important public health problem in the world due to uncontrolled enzootic rabies. Although rabies associated fatalities may be prevented with timely immunoprophylaxis, but till date a therapeutic molecule has remained elusive. We investigated the role of rhuIFN α-2a in murine model challenged with rabies virus. Titre of 10(4.25) LD50/0.03 ml of 10% w/v RV CVS stock suspension were obtained. Based on 1LD50 titre, challenge dose of 50 LD 50 was administered along with rhuIFN α-2a with pre-exposure (primed) and post-exposure with the rabies virus. Both showed increased survival time as compared with the virus controls. These findings suggest that the rhuIFN α-2a might have some anti-viral activity, which can be used for the treatment of rabies infection. Further research on the efficacy of interferon along with anti-viral drugs for the treatment will be helpful in designing combination therapy against the disease.

Preparing high-titer virus and performing accurate titer determination are critical to subsequent experiments. However, not all applied recombinant rabies viruses, such as the L-deleted virus, are equipped with fluorescent proteins for titration by fluorescence-activated cell sorting (FACS). Here, we present a quantitative reverse-transcription PCR (RT-qPCR) approach for titrating recombinant rabies virus.

Unlabelled: The genus includes seventeen viral species able to cause rabies, an acute and almost invariably fatal encephalomyelitis of mammals. Rabies virus (RABV), which represents the type species of the genus, is a multi-host pathogen that over the years has undergone multiple events of host-switching, thus occupying several geographical and ecological niches. In contrast, non-RABV lyssaviruses are mainly confined within a single natural host with rare spillover events.

Rabies is a serious zoonotic disease caused by the rabies virus (RABV). Despite the successful development of vaccines and efforts made in drug discovery, rabies is incurable. Therefore, development of novel drugs is of interest to the scientific community.

Rabies is a deadly neurotropic, zoonotic disease with a mortality rate of 100% after symptoms appear. Rabies virus (RABV) is the primary cause of rabies disease in humans, and it mainly spreads via dog bites in developing countries. Over the course of RABV evolution, multiple RABV variants, called clades, have emerged.

GABAergic neurons in basal forebrain (BF) nuclei project densely to all layers of the mouse main olfactory bulb (OB), the first relay in odor information processing. However, BF projection neurons are diverse and the contribution of each subtype to odor information processing is not known. In the present study, we used retrograde and anterograde tracing methods together with whole-brain light-sheet analyses, patch-clamp recordings coupled with optogenetic and chemogenetic approaches during spontaneous odor discrimination, and go/no-go odor discrimination/learning tests to characterize the synaptic targets in the OB of BF calretinin-expressing (CR+) GABAergic cells and to reveal their functional implications.
