Description
CD1d expression by thymocytes is required to select iNKT cells. When CD1d is expressed only on thymocytes (pLck-CD1d tg mice), iNKT cells are hyperresponsive to antigen stimulation suggesting that, in physiological conditions, these cells undergo functional education mediated by additional CD1d-expressing cells. Here, we investigated the mechanisms of this functional education. We find that peripheral iNKT cells from pLck-CD1d tg mice express significantly less SHP-1, a tyrosine phosphatase negatively regulating TCR signaling, than WT cells. iNKT cells from heterozygous SHP-1-mutated motheaten mice, displaying similar SHP-1 reduction as pLck-CD1d tg iNKT cells, are antigen-hyperresponsive. Restoring normal CD1d expression in pLck-CD1d tg mice normalizes SHP-1 expression and responsiveness of iNKT cells. In WT mice, iNKT cells upregulate SHP-1 and decrease responsiveness upon emigration from thymus to periphery. This depends on contacts with CD1d-expressing DCs. iNKT cell functional education is therefore controlled by DCs via tuning SHP-1 expression level in the periphery.

Description
Heat stress is one of the most prominent and deleterious environmental threads affecting plant growth and development. Upon high temperatures, plants launch specialized gene expression programs that promote stress protection and survival. These programs involve global and specific changes at the transcriptional and translational levels. However the coordination of these processes and their specific role in the establishment of the heat stress response is not fully elucidated.

Description
UV-B radiation affects leaf growth in a wide range of species. In this work, we demonstrate that UV-B levels present in solar radiation inhibits maize leaf growth without causing any other visible stress symptoms, including accumulation of DNA damage. We conducted kinematic analyses of cell division and expansion to understand the impact of UV-B radiation on these cellular processes. Our results demonstrate that the decrease in leaf growth is a consequence of a reduction in cell production, and a shortened growth zone (GZ) in UV-B irradiated leaves. To determine the molecular pathways involved in UV-B inhibition of leaf growth, we performed RNA sequencing on isolated GZ tissues of control and UV-B exposed plants. Our results show a link between the observed leaf growth inhibition and the expression of specific cell cycle and developmental genes, including Growth Regulating Factors (GRFs) and transcripts for proteins participating in different hormone pathways. Overall design: Factorial design with two factors: Treatment (control vs UV-B) x Zone I (0-1cm from base of the leaf), 2 (1-2cm from base of the leaf) and 3 (2-3cm from base of the leaf), 3 replicates

Description
IKKbeta is a subunit of the IkB kinase (IKK) complex required for NF-kB activation in response to pro-inflammatory signals. NF-kB regulates the expression of many genes involved in inflammation, immunity and apoptosis, and also controls cell proliferation and differentiation in different tissues; however, its function in skin physiopathology remains controversial. We here report the alterations caused by increased IKKbeta activity in basal cells of the skin of transgenic mice.

IKKbeta leads to an inflammatory skin disease resembling interface dermatitis.
