Abstract
Chemotherapy-related cognitive deficits (CRCI) as one of the common adverse drug reactions during chemotherapy that manifest as memory, attention, and executive function impairments. However, there are still no effective pharmacological therapies for the treatment of CRCI. Natural compounds have always inspired drug development and numerous natural products have shown potential therapeutic effects on CRCI. Nevertheless, improving the brain targeting of natural compounds in the treatment of CRCI is still a problem to be overcome at present and in the future. Accumulated evidence shows that nose-to-brain drug delivery may be an excellent carrier for natural compounds. Therefore, we reviewed natural products with potential anti-CRCI, focusing on the signaling pathway of these drugs' anti-CRCI effects, as well as the possibility and prospect of treating CRCI with natural compounds based on nose-to-brain drug delivery in the future. In conclusion, this review provides new insights to further explore natural products in the treatment of CRCI.

Abstract
Murine norovirus (MNV) is a positive-sense, plus-stranded RNA virus in the Caliciviridae family. Viruses in this family replicate in the intestine and are transmitted by the fecal-oral route. MNV is related to the human noroviruses, which cause the majority of nonbacterial gastroenteritis worldwide. Given the technical challenges in studying human norovirus, MNV is often used to study mechanisms in norovirus biology since it combines the availability of a cell culture and reverse genetics system with the ability to study infection in the native host. Adding to our previous protocol collection, here we describe additional techniques that have since been developed to study MNV biology. © 2023 The Authors. Current Protocols published by Wiley Periodicals LLC.

Abstract
The brain is protected from toxins by a tightly regulated network of specialized cells, including endothelial cells, pericytes, astrocyes, and neurons, known collectively as the blood-brain barrier (BBB). This selectively permeable barrier permits only the most crucial molecules essential for brain function to enter and employs a number of different mechanisms to prevent the entry of potentially harmful toxins and pathogens. In addition to a physical barrier comprised of endothelial cells that form tight junctions to restrict paracellular transport, there is an active protective mechanism made up of energy-dependent transporters that efflux compounds back into the bloodstream. Two of these ATP-binding cassette (ABC) transporters are highly expressed at the BBB: P-glycoprotein (P-gp, encoded by the ABCB1 gene) and ABCG2 (encoded by the ABCG2 gene). Although a number of in vitro and in vivo systems have been developed to examine the role that ABC transporters play in keeping compounds out of the brain, all have inherent advantages and disadvantages. Zebrafish (Danio rerio) have become a model of interest for studies of the BBB due to the similarities between the zebrafish and mammalian BBB systems. In this review, we discuss what is known about ABC transporters in zebrafish and what information is still needed before the zebrafish can be recommended as a model to elucidate the role of ABC transporters at the BBB.

Sci Rep 2020; 10:395. [PMID: 31942034 PMCID: PMC6962329 DOI: 10.1038/s41598-019-57384-w] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2019] [Accepted: 12/30/2019] [Indexed: 11/09/2022] Open
Abstract
The Plasmodium falciparum gametocyte surface protein, Pfs48/45, is a potential target for malaria transmission-blocking vaccines. However, due to its size and complexity, expression of the full-length protein has been difficult, leading to focus on the C-terminal six cysteine domain (6C) with the use of fusion proteins to facilitate expression and folding. In this study, we utilized the baculovirus system to evaluate the expression of three Pfs48/45 proteins including the full-length protein, the 6C domain fragment and the 6C domain mutant to prevent glycosylation. Expression of the recombinant Pfs48/45 proteins was conducted in super Sf9 cells combined with the use of tunicamycin to prevent N-glycosylation. The proteins were then evaluated as immunogens in mice to demonstrate the induction of functionally active polyclonal antibody responses as measured in the standard membrane feeding assay (SMFA). Only the 6C protein was found to exhibit significant transmission-reducing activity. Further characterization of the biologically active 6C protein demonstrated it was homogeneous in terms of size, charge, conformation, absence of glycosylation, and containing proper disulfide bond pairings. This study presents an alternative expression system, without the need of a fusion protein partner, for the Pfs48/45 6C protein fragment including further evaluation as a potential transmission-blocking vaccine candidate.

Using the lentiviral vector system to stably express chicken P-gp and BCRP in MDCK cells for screening the substrates and studying the interplay of both transporters. Arch Toxicol 2018; 92:2027-2042.

Abstract
Transporters P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP) are known to influence the pharmacokinetics and toxicity of substrate drugs. However, no detailed information is as yet available about functional activity and substrate spectra of chicken P-gp and BCRP. In this study, BCRP single and BCRP/P-gp double-transfected MDCK cell lines (named MDCK-chAbcg2 and MDCK-chAbcg2/Abcb1, respectively) were generated using lentiviral vector system to develop reliable systems for screening the substrates for these two transporters and study the interplay between them. The constructed cell lines significantly expressed functional exogenous proteins and expression persisted for at least 50 generations with no decrease. Enrofloxacin, ciprofloxacin, tilmicosin, sulfadiazine, ampicillin and clindamycin were classified as the substrates of chicken P-gp according to the rules suggested by FDA, as their net efflux ratios were greater than two. Similarly, enrofloxacin, ciprofloxacin, tilmicosin, florfenicol, ampicillin and clindamycin were classified as the substrates of BCRP. Among these drugs, enrofloxacin, ciprofloxacin, tilmicosin, ampicillin, and clindamycin were the cosubstrates of P-gp and BCRP, however, chicken BCRP and P-gp exhibit different affinities to the shared substrates at different concentrations by blocking either one or both transport with specific inhibitors in the coexpression system. It was also found that ceftiofur, amoxicillin and doxycycline were not substrates of either chicken BCRP or the substrates of chicken P-gp. These constructed cell models provide useful systems for high-throughput screening of the potential substrates of chicken BCRP and P-gp as well as the drug-drug interaction mediated via chicken BCRP and P-gp.
