Phytoliths in the inflorescence of Poaceae plants can be of high taxonomic value in some archaeological contexts and provide insight into plant taxonomy and crop domestication processes. In this study, phytoliths in every inflorescence bract of 38 common Panicoideae weeds and minor crops in China were studied. Based on dissection of the inflorescence into different bracts using a treatment that retained the phytoliths anatomical position, observations of inflorescence phytoliths types and distribution were described in detail. α-D-Glucose anhydrous nmr We found that Interdigitating, Blocky amoeboid, Rectangular dentate, and Elongate dendritic with multi tent-like arch tops were of higher taxonomic value than the other types in our studied species. Both morphological and morphometric traits of the Interdigitating were summarized and compared with previous studies; the findings suggested that genus level discrimination of some Paniceae species could be reliable, and tribe/species level discrimination might be feasible. The phytoliths in the involucre of domesticated and wild type Coix lacryma-jobi provided insight into the domestication process of this plant. Our data also indicated that phytolith production in the inflorescence bracts might be under the genetic and molecular control of inflorescence development. Thus, the findings of this study could assist future studies in plant taxonomy and archaeobotany.

MICA/B gene polymorphisms, expression levels and the amount of soluble MICA/B in the serum have been linked to autoimmune diseases, infections, and cancer. In hematopoietic stem cell transplantation, MICA matching between donor and patient has been correlated with reduced acute and chronic graft-vs.-host disease and improved survival. Hence, we developed an extremely cost-efficient high-throughput workflow for genotyping MICA/B for newly registered potential stem cell donors. Since mid-2017, we have genotyped over two million samples using NGS amplicon sequencing for MICA/B exons 2-5. In donors of German origin, MICA*008 is the most common MICA allele with a frequency of 42.3%. It is followed by MICA*002 (11.7%) and MICA*009 (8.8%). The three most common MICB alleles are MICB*005 (43.9%), MICB*004 (21.7%), and MICB*002 (18.9%). In general, MICB is less diverse than MICA and only 6 alleles, instead of 15, account for a cumulative allele frequency of 99.5%. In 0.5% of the samples we observed at least one allele of MICA or MICB which has so far not been reported to the IPD/IMGT-HLA database. By providing MICA/B typed voluntary donors, clinicians become empowered to include MICA/B into their donor selection process to further improve unrelated hematopoietic stem cell transplantation.

But how stroke affects the progression of cancer remains unclear. We inoculated B16 tumor cells (2 × 105) subcutaneously before distal middle cerebral artery occlusion (dMCAO) or sham surgery in C57BL/6 mice and found that compared to sham operated mice, dMCAO mice developed significantly increased tumor volume and were accompanied by lower survival rate. To explore the underlying mechanism, we performed RNA-sequencing analysis of the tumor tissue from mice with or without stroke and found prominent upregulation of lipocalin 2 (LCN2) in the tumor from stroke mice compared to those from sham mice. Using quantitative reverse transcription-PCR, we confirmed increased mRNA expression of LCN2 as well as anti-inflammatory cytokines-Arg1, IL-10, and decreased mRNA level of pro-inflammatory cytokines-IL-6, IL-23 in the tumor of cancer-bearing stroke mice. Both immunofluorescence staining and flow cytometry analysis revealed that increased expression of LCN2 was mainly derived from the polymorphonuclear myeloid derived suppressor cells (PMN-MDSCs) in the tumor. We also found that stroke reduced the PMN-MDSCs in the peripheral blood, but increased PMN-MDSCs in the tumor of the cancer-bearing mice after stroke. In conclusion, cerebral ischemic stroke may exacerbate cancer progression by increasing LCN2 expression in PMN-MDSCs, which turns out to be a promising therapeutic target to suppress cancer progression after ischemic stroke.

Epidemiological data implicate NK cells in human pregnancy outcomes. Discoveries using mouse NK cells have guided subsequent advances in human NK cell biology. However, it remains challenging to identify mouse and human uterine NK (uNK) cell function(s) because of the dynamic changes in the systemic-endocrinological and local uterine structural microenvironments during pregnancy. This review discusses functional similarities and differences between mouse and human NK cells at the maternal-fetal interface.

In this study, we applied high-dimensional single-cell mass cytometry to phenotypically characterize PBMC from patients with new-onset (N-T1D) and long-standing type 1 diabetes, Hashimoto's thyroiditis (HT), Graves' disease and autoimmune Addison's disease (AD), as well as healthy controls. The frequency of CD20loCD27hiCD38hiHLA-DRint plasmablasts, CD86+CD14loCD16+ non-classical monocytes and two subsets of CD56dimHLA-DR+IFN-γ+ NK cells were increased in patients with HT. Subsets of CD56dimCD69+HLA-DR- NK cells and CD8+ TEMRA cells, both expressing IFN-γ, were expanded and reduced, respectively, in the N-T1D group. In addition, patients with AD were characterized by an increased percentage of central memory CD8+ T cells that expressed CCR4, GATA3, and IL-2. We demonstrate that patients with N-T1D, HT, and AD had altered frequencies of distinct subsets within antigen-presenting and cytotoxic cell lineages.
