    Description: Previous reports have shown that γδ T cells are important for the elimination of malaria parasites in humans and mice. However, how γδ T cells are involved in protective immunity against blood-stage malaria remains unknown. We infected γδ T-cell–deficient (TCRδ-KO) mice and control wild-type mice with Plasmodium berghei XAT, which is a nonlethal strain. Although infected red blood cells were eliminated within 30 d after infection, TCRδ-KO mice could not clear the infected red blood cells, showed high parasitemia, and eventually died. Therefore, γδ T cells are essential for clearance of the parasites. Here, we found that γδ T cells play a key role in dendritic cell activation after Plasmodium infection. On day 5 postinfection, γδ T cells produced IFN-γ and expressed CD40 ligand during dendritic cell activation. These results suggest that γδ T cells enhance dendritic cell activation via IFN-γ and CD40 ligand–CD40 signaling. This hypothesis is supported strongly by the fact that in vivo induction of CD40 signaling prevented the death of TCRδ-KO mice after infection with P. berghei XAT. This study improves our understanding of protective immunity against malaria and provides insights into γδ T-cell–mediated protective immunity against various infectious diseases.

    Description: Full-length complementary DNAs (cDNAs) are essential for the correct annotation of genomic sequences and for the functional analysis of genes and their products. We isolated 155,144 RIKEN Arabidopsis full-length (RAFL) cDNA clones. The 3'-end expressed sequence tags (ESTs) of 155,144 RAFL cDNAs were clustered into 14,668 nonredundant cDNA groups, about 60% of predicted genes. We also obtained 5' ESTs from 14,034 nonredundant cDNA groups and constructed a promoter database. The sequence database of the RAFL cDNAs is useful for promoter analysis and correct annotation of predicted transcription units and gene products. Furthermore, the full-length cDNAs are useful resources for analyses of the expression profiles, functions, and structures of plant proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seki, Motoaki -- Narusaka, Mari -- Kamiya, Asako -- Ishida, Junko -- Satou, Masakazu -- Sakurai, Tetsuya -- Nakajima, Maiko -- Enju, Akiko -- Akiyama, Kenji -- Oono, Youko -- Muramatsu, Masami -- Hayashizaki, Yoshihide -- Kawai, Jun -- Carninci, Piero -- Itoh, Masayoshi -- Ishii, Yoshiyuki -- Arakawa, Takahiro -- Shibata, Kazuhiro -- Shinagawa, Akira -- Shinozaki, Kazuo -- New York, N.Y. -- Science. 2002 Apr 5;296(5565):141-5.

    Description: Functional analysis of a genome requires accurate gene structure information and a complete gene inventory. A dual experimental strategy was used to verify and correct the initial genome sequence annotation of the reference plant Arabidopsis. Sequencing full-length cDNAs and hybridizations using RNA populations from various tissues to a set of high-density oligonucleotide arrays spanning the entire genome allowed the accurate annotation of thousands of gene structures. We identified 5817 novel transcription units, including a substantial amount of antisense gene transcription, and 40 genes within the genetically defined centromeres. This approach resulted in completion of approximately 30% of the Arabidopsis ORFeome as a resource for global functional experimentation of the plant proteome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamada, Kayoko -- Lim, Jun -- Dale, Joseph M -- Chen, Huaming -- Shinn, Paul -- Palm, Curtis J -- Southwick, Audrey M -- Wu, Hank C -- Kim, Christopher -- Nguyen, Michelle -- Pham, Paul -- Cheuk, Rosa -- Karlin-Newmann, George -- Liu, Shirley X -- Lam, Bao -- Sakano, Hitomi -- Wu, Troy -- Yu, Guixia -- Miranda, Molly -- Quach, Hong L -- Tripp, Matthew -- Chang, Charlie H -- Lee, Jeong M -- Toriumi, Mitsue -- Chan, Marie M H -- Tang, Carolyn C -- Onodera, Courtney S -- Deng, Justine M -- Akiyama, Kenji -- Ansari, Yasser -- Arakawa, Takahiro -- Banh, Jenny -- Banno, Fumika -- Bowser, Leah -- Brooks, Shelise -- Carninci, Piero -- Chao, Qimin -- Choy, Nathan -- Enju, Akiko -- Goldsmith, Andrew D -- Gurjal, Mani -- Hansen, Nancy F -- Hayashizaki, Yoshihide -- Johnson-Hopson, Chanda -- Hsuan, Vickie W -- Iida, Kei -- Karnes, Meagan -- Khan, Shehnaz -- Koesema, Eric -- Ishida, Junko -- Jiang, Paul X -- Jones, Ted -- Kawai, Jun -- Kamiya, Asako -- Meyers, Cristina -- Nakajima, Maiko -- Narusaka, Mari -- Seki, Motoaki -- Sakurai, Tetsuya -- Satou, Masakazu -- Tamse, Racquel -- Vaysberg, Maria -- Wallender, Erika K -- Wong, Cecilia -- Yamamura, Yuki -- Yuan, Shiaulou -- Shinozaki, Kazuo -- Davis, Ronald W -- Theologis, Athanasios -- Ecker, Joseph R -- New York, N.Y. -- Science. 2003 Oct 31;302(5646):842-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Plant Gene Expression Center, Albany, CA 94710, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14593172" target="_blank"〉PubMed〈/a〉

    Description: Copy number variants (CNVs) are major contributors to genetic disorders. We have dissected a region of the 16p11.2 chromosome--which encompasses 29 genes--that confers susceptibility to neurocognitive defects when deleted or duplicated. Overexpression of each human transcript in zebrafish embryos identified KCTD13 as the sole message capable of inducing the microcephaly phenotype associated with the 16p11.2 duplication, whereas suppression of the same locus yielded the macrocephalic phenotype associated with the 16p11.2 deletion, capturing the mirror phenotypes of humans. Analyses of zebrafish and mouse embryos suggest that microcephaly is caused by decreased proliferation of neuronal progenitors with concomitant increase in apoptosis in the developing brain, whereas macrocephaly arises by increased proliferation and no changes in apoptosis. A role for KCTD13 dosage changes is consistent with autism in both a recently reported family with a reduced 16p11.2 deletion and a subject reported here with a complex 16p11.2 rearrangement involving de novo structural alteration of KCTD13. Our data suggest that KCTD13 is a major driver for the neurodevelopmental phenotypes associated with the 16p11.2 CNV, reinforce the idea that one or a small number of transcripts within a CNV can underpin clinical phenotypes, and offer an efficient route to identifying dosage-sensitive loci.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3366115/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3366115/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Golzio, Christelle -- Willer, Jason -- Talkowski, Michael E -- Oh, Edwin C -- Taniguchi, Yu -- Jacquemont, Sebastien -- Reymond, Alexandre -- Sun, Mei -- Sawa, Akira -- Gusella, James F -- Kamiya, Atsushi -- Beckmann, Jacques S -- Katsanis, Nicholas -- F32MH087123/MH/NIMH NIH HHS/ -- HD06286/HD/NICHD NIH HHS/ -- MH-084018/MH/NIMH NIH HHS/ -- MH-091230/MH/NIMH NIH HHS/ -- P50 MH094268/MH/NIMH NIH HHS/ -- P50 MH094268-02/MH/NIMH NIH HHS/ -- R01 MH091230/MH/NIMH NIH HHS/ -- R01 MH092443/MH/NIMH NIH HHS/ -- England -- Nature. 2012 May 16;485(7398):363-7. doi: 10.1038/nature11091.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Human Disease Modeling and Department of Cell biology, Duke University, Durham, North Carolina 27710, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22596160" target="_blank"〉PubMed〈/a〉

    Description: Regulatory mechanisms governing the sequence from progenitor cell proliferation to neuronal migration during corticogenesis are poorly understood. Here we report that phosphorylation of DISC1, a major susceptibility factor for several mental disorders, acts as a molecular switch from maintaining proliferation of mitotic progenitor cells to activating migration of postmitotic neurons in mice. Unphosphorylated DISC1 regulates canonical Wnt signalling via an interaction with GSK3beta, whereas specific phosphorylation at serine 710 (S710) triggers the recruitment of Bardet-Biedl syndrome (BBS) proteins to the centrosome. In support of this model, loss of BBS1 leads to defects in migration, but not proliferation, whereas DISC1 knockdown leads to deficits in both. A phospho-dead mutant can only rescue proliferation, whereas a phospho-mimic mutant rescues exclusively migration defects. These data highlight a dual role for DISC1 in corticogenesis and indicate that phosphorylation of this protein at S710 activates a key developmental switch.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3088774/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3088774/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ishizuka, Koko -- Kamiya, Atsushi -- Oh, Edwin C -- Kanki, Hiroaki -- Seshadri, Saurav -- Robinson, Jon F -- Murdoch, Hannah -- Dunlop, Allan J -- Kubo, Ken-ichiro -- Furukori, Keiko -- Huang, Beverly -- Zeledon, Mariela -- Hayashi-Takagi, Akiko -- Okano, Hideyuki -- Nakajima, Kazunori -- Houslay, Miles D -- Katsanis, Nicholas -- Sawa, Akira -- DK-072301/DK/NIDDK NIH HHS/ -- DK-075972/DK/NIDDK NIH HHS/ -- G0600765/Medical Research Council/United Kingdom -- HD-04260/HD/NICHD NIH HHS/ -- MH-069853/MH/NIMH NIH HHS/ -- MH-084018/MH/NIMH NIH HHS/ -- MH-085226/MH/NIMH NIH HHS/ -- MH-088753/MH/NIMH NIH HHS/ -- MH-091230/MH/NIMH NIH HHS/ -- R01 DK072301/DK/NIDDK NIH HHS/ -- R01 DK075972/DK/NIDDK NIH HHS/ -- R01 DK075972-06/DK/NIDDK NIH HHS/ -- R01 HD042601/HD/NICHD NIH HHS/ -- R01 HD042601-10/HD/NICHD NIH HHS/ -- R01 MH091230/MH/NIMH NIH HHS/ -- R01 MH092443/MH/NIMH NIH HHS/ -- England -- Nature. 2011 May 5;473(7345):92-6. doi: 10.1038/nature09859.
