In this study, we used Foxp3‐fatemapping mice to examine the cell lineage stability of Treg cells in pregnancy. Ex‐Foxp3 cells were identified in gestational tissues. However, Treg cells retained lineage stability with no increased ex‐Foxp3 generation, regardless of inflammatory challenges that induce preterm birth.

Tangle analysis of DNA unlinking by the Xer/FtsK system(Knots and soft-matter physics: Topology of polymers and related topics in physics, mathematics and biology) [PDF]
この論文は国立情報学研究所の電子図書館事業により電子化されました。DNAに作用する部位特異的組み換え酵素の働きは、タングルを用いてモデル化され、得られるタングル方程式を数学の結果を用いて解くことにより、部位特異的酵素の働きのトポロジーの特徴付けが出来る。ここでは、Grainge等(2007)によって示された部位特異的Xer/FtsKシステムによるDNA絡み目解消操作の解析を行い、その特徴付けを述べる。特にその作用を特徴付ける主要なタングルが有理タングルとなることを示す。The action of ...

Principles of genetic circuit design [PDF]
Cells navigate environments, communicate and build complex patterns by initiating gene expression in response to specific signals. Engineers seek to harness this capability to program cells to perform tasks or create chemicals and materials that match ...

The X Factor in Immunity: Sex Differences Shaped by the X Chromosome
ABSTRACT There are sex differences with immune responses where females exhibit stronger immune responses compared to males. Both sex hormones and sex chromosome differences between males and females contribute to the observed sex differences with innate and adaptive immune cell composition and function.

Homologous Recombination: To Fork and Beyond [PDF]
Accurate completion of genome duplication is threatened by multiple factors that hamper the advance and stability of the replication forks. Cells need to tolerate many of these blocking lesions to timely complete DNA replication, postponing their repair ...

Genetic targeting of select populations of cells in the mouse nervous system is often hampered by a lack of selectivity, as candidate genes for such targeting are commonly expressed by multiple cell populations, also in the same region.

Binary recombinase systems for high-resolution conditional mutagenesis [PDF]
Conditional mutagenesis using Cre recombinase expressed from tissue specific promoters facilitates analyses of gene function and cell lineage tracing. Here, we describe two novel dual-promoter-driven conditional mutagenesis systems designed for greater ...

Cluster J Mycobacteriophages: Intron Splicing in Capsid and Tail Genes [PDF]
Bacteriophages isolated on Mycobacterium smegmatis mc2155 represent many distinct genomes sharing little or no DNA sequence similarity. The genomes are architecturally mosaic and are replete with genes of unknown function.

Differential recognition of the Multiple Banded Antigen isoforms across Ureaplasma parvum and Ureaplasma urealyticum species by monoclonal antibodies [PDF]
Two separate species of Ureaplasma have been identified that infect humans: Ureaplasma parvum and Ureaplasma urealyticum. Most notably, these bacteria lack a cell wall and are the leading infectious organism associated with infection-related induction of

The Tn916/Tn1545 Family of Conjugative Transposon [PDF]
The conjugative transposon Tn916 was first discovered in the late 1970s and is, together with the related conjugative transposon Tn1545, the paradigm of a large family of related conjugative transposons known as the Tn916/Tn1545 family, which are found ...
