Description
We disprove that the impaired Myd88-dependent proinflammatory response of neonatal monocytes is a correlate for immaturity and confirm it as display of transient alarmin-mediated stress tolerization. We find a strong inducibility of TRIF-dependent genes in neonatal monocytes by LPS but a barely detectable expression at baseline.

Description
The influenza A(H1N1)pdm09 virus caused a global flu pandemic in 2009 and contributes to seasonal epidemics. Different treatment and prevention options for influenza have been developed and applied with limited success. Here we report that an Akt inhibitor MK2206 possesses potent antiviral activity against influenza A(H1N1)pdm09 virus in vitro. We showed that MK2206 blocks the entry of different A(H1N1)pdm09 strains into cells. Moreover, MK2206 prevented A(H1N1)pdm09-mediated activation of cellular signaling pathways and the development of cellular immune responses. Importantly, A(H1N1)pdm09 virus was unable to develop resistance to MK2206. Thus, MK2206 is a potent anti-influenza A(H1N1)pdm09 agent.

Description
Hdac3 is an important target of HDAC inhibitors used in the treatment of cutaneous T cell lymphoma. In order to gain an understanding of Hdac3 function in T cells,we deleted Hdac3 from early mouse thymocytes using LCK-Cre. Hdac3 deletion resulted in a loss of single positive thymocytes due to a defect in positive selection at the double positive (DP) stage of thymocyte development. To better characterize this defect, we sorted the DP1 and DP2 populations to for gene expression profiling. Overall design: Total RNA was extracted from DP1 (GFP+CD4+CD8+CD5loTCRblo) or DP2 (GFP+CD4+CD8+CD5hiTCRbint) thymocytes isolated by FACS from Hdac3+/+ or Hdac3F/F LCK-Cre+ animals. Libraries were constructed from rRNA-depleted total RNA pools to identify altered gene expression in DP populations following Hdac3 deletion.

Description
Atherosclerosis is a transmural chronic inflammatory condition of small and large arteries that is associated with adaptive immune responses at all disease stages. However, impacts of adaptive immune reactions on clinically apparent atherosclerosis such as intima lesion (plaque) rupture, thrombosis, myocardial infarction, and aneurysm largely remain to be identified. It is increasingly recognized that leukocyte infiltrates in plaque, media, and adventitia are distinct but their specific roles have not been defined. To map these infiltrates, we employed laser capture microdissection (LCM) to isolate the three arterial wall laminae using apoE-/- mouse aorta as a model. RNA from LCM-separated tissues was extracted and large scale whole genome expression microarrays were prepared. We observed that the quality of the resulting gene expression maps was compromised by tissue RNA carried over from adjacent laminae during LCM. To account for these flaws, we established quality controls and algorithms to improve the predictive power of LCM-derived microarray data. Our approach creates robust transcriptome atlases of normal and atherosclerotic aorta. Assessing LCM transcriptomes for immunity-related mRNAs indicated markedly distinctive gene expression patterns in the three laminae of the atherosclerotic aorta. These mouse mRNA expression data banks can now be mined to address a wide range of questions in cardiovascular biology.

Description
Advances in pluripotent stem cell and reprogramming technologies have given hope of generating hematopoietic stem cells (HSC) in culture. To succeed, greater understanding of the self-renewing HSC during human development is required. We discovered that glycophosphatidylinositol-anchored surface protein GPI-80 (Vanin 2) defines a distinct subpopulation of human fetal hematopoietic stem/progenitor cells (HSPC) with self-renewal ability. CD34+CD90+CD38-GPI-80+ HSPC were the sole population that maintained proliferative potential and undifferentiated state in bone marrow stroma co-culture, and engrafted in immunodeficient mice. GPI-80 expression also enabled tracking of HSC migration between human fetal hematopoietic niches. The most highly enriched surface protein in GPI-80+ HSPC as compared to their progeny was Integrin alpha-M (ITGAM), which in leukocytes cooperates with GPI-80 to support migration. Knockdown of either GPI-80 or ITGAM was sufficient to perturb undifferentiated HSPC in stroma co-culture. These findings indicate that human fetal HSC utilize common mechanisms with leukocytes for cell-cell interactions governing HSC self-renewal.

Description
The amygdala is a prominent region of the brain processing stress-related emotion and vigilance. Additionally it is known that the serotonergic system is strongly involved in stress response and adaptation. The serotonin transporter (5-HTT) as key regulator of serotonergic activity in the brain is associated with stress-related neuropsychiatric disorders as well as heightened trait anxiety/dysphoria and exaggerated response to fear and environmental stress in humans. Also 5-HTT knockout mice display increased anxiety- and depression-related behaviors, altered stress reactivity and stress-coping abilities, gene expression differences and altered dendritic morphology.
