Phytohormonal homeostasis, chloroplast stability, and heat shock transcription pathways related to the adaptability of creeping bentgrass species to heat stress.

Creeping bentgrass (Agrostis stolonifera) is a cool-season perennial turfgrass and is frequently utilized in high-quality turf areas. However, a poor to moderate resistance to heat stress limits its promotion and utilization in transitional and worm climate zones. The objectives of the study were to assess the heat tolerance of 18 creeping bentgrass genotypes in the field and to further uncover differential mechanisms of heat tolerance between heat-tolerant and heat-sensitive genotypes.

Infiltrating macrophages and interferon gamma rather than renal genotype dictate heightened crescentic glomerulonephritis.

Apex1 safeguards genomic stability to ensure a cytopathic T cell fate in autoimmune disease models.

T cells have a remarkable capacity to clonally expand, a process that is intricately linked to their effector activities. As vigorously proliferating T cell also incur substantial DNA lesions, how the dividing T cells safeguard their genomic integrity to allow the generation of T effector cells remains largely unknown. Here we report the identification of the apurinic/apyrimidinic endonuclease-1 (Apex1) as an indispensable molecule for the induction of cytopathic T effectors in mouse models.

Demographic data, initial clinical symptoms, on-admission vital signs, comorbidities, laboratory tests and imaging examination, treatment, and follow-up were compared between the two groups.

Tracking of serum lipids from prepuberty to young adulthood: results from the KiGGS cohort study.

Background: Universal lipid screening in childhood for early detection and treatment of familial hypercholesterolemia is under discussion, but will also detect children with multifactorial dyslipidemia. Results from population-based studies can support the design of public health strategies. As few previous studies considered pubertal changes in serum lipid levels, we examined tracking of serum lipids from prepuberty to young adulthood in a population-based cohort.

Mechanosensing regulates pDC activation in the skin through NRF2 activation.

Plasmacytoid DCs (pDCs) infiltrate the skin, chronically produce type I interferon (IFN-I), and promote skin lesions and fibrosis in autoimmune patients. However, what controls their activation in the skin is unknown. Here, we report that increased stiffness inhibits the production of IFN-I by pDCs.

Altered X-chromosome inactivation of the TLR7/8 locus and heterogeneity of pDCs in systemic sclerosis.

Systemic sclerosis (SSc) is an autoimmune disease that has a strong female predominance. Both the X-linked TLR7 and TLR8 can induce type I IFN (IFN-I) by plasmacytoid DCs (pDCs), which can promote fibrosis. We identified five subclusters of pDCs, including ISGhigh clusters that were over-represented in SSc patients.
