When animals encounter conflict they initiate and escalate aggression to establish and maintain a social hierarchy. The neural mechanisms by which animals resolve fighting behaviors to determine such social hierarchies remain unknown. We identified t

Establishment of a MAGI-derived indicator cell line that detects the Nef enhancement of HIV-1 infectivity with high sensitivity

Autor: Michiyuki Matsuda, Minoru Tobiume, Masashi Tatsumi, Mikako Takahoko

Publikováno v: Journal of Virological Methods. 97:151-158

The Nef protein of the simian and human immunodeficiency viruses (SIV and HIV) is regarded as one of the critical determinants of the pathogenicity of HIV-1 in vivo. The positive effect of Nef on viral replication is examined most easily in vitro by

Requirement of Nef for HIV-1 infectivity is biased by the expression levels of Env in the virus-producing cells and CD4 in the target cells

Publikováno v: Archives of Virology. 146:1739-1751

The nef gene of human immunodeficiency virus type 1 (HIV-1) encodes a 27 to 34 kDa myristoylated protein, which enhances viral infectivity in a single-round infection assay. The level of Nef enhancement of HIV-1 infectivity depends on the viral strai

Publikováno v: AIDS Research and Human Retroviruses. 17:1083-1087

We constructed an infectious DNA clone of the HIV-1 A/G recombinant 97GH-AG2, which was isolated in Ghana in 1997 and was classified originally as subtype A. By phylogenetic and recombination breakpoint analyses, p97GH-AG2 was grouped in the circulat

Publikováno v: Mutation Research/Genetic Toxicology. 371:203-214

The effect of Tochu tea, which is an aqueous extract of Eucommia ulmoides leaves and a popular beverage in Japan, on the urine mutagenicity before and after ingestion of raw fish and cooked beef was studied using Salmonella typhimurium YG1024. Urines

Publikováno v: Nature neuroscience. 13(11)

The zebrafish dorsal habenula (dHb) shows conspicuous asymmetry in its connection with the interpeduncular nucleus (IPN) and is equivalent to the mammalian medial habenula. Genetic inactivation of the lateral subnucleus of dHb (dHbL) biased fish towa

Identification of the zebrafish ventral habenula as a homolog of the mammalian lateral habenula

Publikováno v: The Journal of neuroscience : the official journal of the Society for Neuroscience. 30(4)

The mammalian habenula consists of the medial and lateral habenulae. Recent behavioral and electrophysiological studies suggested that the lateral habenula plays a pivotal role in controlling motor and cognitive behaviors by influencing the activity

HuC:Kaede, a useful tool to label neural morphologies in networks in vivo

Autor: Mikako Takahoko, Tomomi Sato, Hitoshi Okamoto

Publikováno v: Genesis (New York, N.Y. : 2000). 44(3)

A simple and efficient procedure for labeling neurons is a prerequisite for investigating the development of neural networks in zebrafish. To label neurons we used Kaede, a fluorescent protein with a photoconversion property allowing conversion from

Publikováno v: Journal of virology. 76(12)

It has been reported that patients infected withnef-defective human immunodeficiency virus type 1 (HIV-1) do not progress to AIDS; however, mutations that abrogate Nef expression are not common in long-term nonprogressors (LTNPs). We postulated that
