The case for plerixafor to replace filgrastim as the optimal agent to mobilize peripheral blood donors for allogeneic hematopoietic cell transplantation. Exp Hematol 2018; 70:1-9.

Abstract
Granulocyte colony-stimulating factor (G-CSF)-stimulated peripheral blood progenitor cells (G-PBs) from either a related or unrelated donor continue to be the preferred donor source for most allogeneic hematopoietic cell transplantation (HCT). Recently, the American Society for Blood and Marrow Transplantation has recommended marrow instead of G-PBs as an unrelated graft source due to its lower rate of chronic graft-versus-host disease (cGVHD). However, the use of marrow is limited by both clinical considerations (slower rate of engraftment and increased donor morbidity) and logistical considerations (use of operating room resources and increased physician utilization), so this recommendation has not been widely adopted. An optimal donor source would include the rapid engraftment characteristic and the low donor morbidity associated with G-PBs and a rate of cGVHD similar to or lower than that of marrow. Recent data suggest that plerixafor mobilized PBs (P-PBs) have the rapid engraftment characteristics of G-PBs in allogeneic HCT with less cGVHD. The biologic mechanism of the lower rate of cGVHD appears to be through mobilization of regulator natural killer cells and plasmacytoid dendritic cell precursors that are associated with lower acute and chronic GVHD compared with G-PBs and rapid engraftment characterized by rapid myeloid-repopulating capacity. We suggest that, based on the experience of the two Phase II clinical trials and the unique biology of plerixafor-mobilized donor product, it should be evaluated in Phase III trials as an approach to replacing G-CSF mobilization for allogeneic HCT.

Abstract
Systemic monitoring of immune system may not precisely outline the local immune status in the uterus. This survey is a continuation of our previous studies on potential usefulness of menstrual blood (MB) immunophenotyping as a tool for investigation of immunological disturbances in pregnancy-related disorders. Peripheral blood (PB) and MB from healthy fertile (n = 15), unexplained recurrent spontaneous abortion (URSA; n = 15), and unexplained infertile women (n = 8) were collected simultaneously in the second day of their menstrual cycle and frequency of natural killer T (NKT)-like cell subpopulations were assessed by flow cytometry. Menstrual blood of all experimental groups contained higher percentage of TCRαβ+, CD45RO+, and CD16- NKT-like cells compared to corresponding PB. Frequency of MB NKT-like cells in unexplained infertile participants was lower than fertile and URSA groups. Compared to normal participants, patients with URSA had lower frequency of PB TCRαβ+ and higher CD16+, while in infertile woman frequencies of PB CD45RO+, CD45RO-, CD16-, IL17+, and MB CD45RO+ NKT-like cells were lower. Although, PB and MB seemingly have the same histological nature, our results showed that MB contained different composition of NKT-like subsets with different cytokine profiles and could be viewed as one potential biological sample for evaluation of patients with infertility and URSA.

Abstract
Type 1 Diabetes Mellitus (T1DM) is characterized by an augmented pro-inflammatory immune state. This contributes to the increased risk for gestational complications observed in T1DM mothers. In normal pregnancies, critical immunological changes occur, including the massive recruitment of lymphocytes, particularly CD56bright NK cells, into early decidua basalis and a 2nd trimester shift towards Type 2 immunity. Decidual CD56bright NK cells arise at least partly from circulating progenitors expressing adhesion molecules SELL and ITGA4 and the chemokine receptors CXCR3 and CXCR4. In vitro studies show that T1DM reduces interactions between blood CD56+ NK cells and decidual endothelial cells by reducing SELL and ITGA4-based interactions. To address the mechanisms by which specific lymphocyte subsets may be recruited from the circulation during pregnancy and whether these mechanisms are altered in T1DM, flow cytometry was used to examine eight peripheral blood lymphocyte subsets (Type 1 (IL18R1+) and Type 2 (IL1RL1+) CD56bright NK, CD56dim NK, NKT and T cells) from control and T1DM women. Blood was collected serially over pregnancy and postpartum, and lymphocytes were compared for expression of homing receptors SELL, ITGA4, CXCR3, and CXCR4. The decline of Type 1/Type 2 immune cells in normal pregnancy was driven by an increase in Type 2 cells that did not occur in T1DM. CD56bright NK cells from control women had the highest expression of all four receptors with greatest expression in 2nd trimester. At this time, these receptors were expressed at very low levels by CD56bright NK cells from TIDM patients. Type 1/Type 2 NKT cell ratios were not influenced by either pregnancy or TIDM. Our results suggest that T1DM alters immunological balances during pregnancy with its greatest impact on CD56bright NK cells. This implicates CD56bright NK cells in diabetic pregnancy complications.

Abstract
PROBLEM Understanding of uterine natural killer (uNK) cell functions during normal pregnancy remains incomplete. METHOD OF STUDY Cloud tag analysis of literature was used to document themes addressed experimentally for uNK cells. Immunohistochemistry, including whole-mount staining of early implantation sites, separation of uNK cells into molecularly distinct subsets, and physiologic measurements in normal and mutant mice, are further advancing understanding of uNK cell biology. RESULTS Literature analyses revealed three key, current uNK cell research themes: angiogenesis, spiral arterial remodeling/pre-eclampsia/hypertension and infertility. UNK cells are being defined as cells potentially regulated by Wnt signaling that are heterogeneous in progenitor source and function and make unique contributions to implantation site development prior to spiral arterial remodeling. CONCLUSION Future studies are poised to define uNK cell progenitor cells, identify the signaling pathways supporting established uNK cell functions and move current understanding of mouse uNK cells to clinical research questions.

Abstract
The pathophysiology of gestational hypertensive disorders is incompletely defined. T lymphocytes are implicated. Both T and natural killer (NK) cells express RAS and, in implantation sites, NK cells are highly enriched. We hypothesized that T cells and/or NK cells contribute to circulatory control during pregnancy. Using radiotelemetry of arterial pressure, heart rate, and activity, mice without T and B cells (genotypes BALB/c-Rag2(-/-) and NOD.scid) were examined at baseline and across pregnancy. These strains differ in NK cell competency, with Rag2(-/-) being normal and NOD.scid impaired. Circulatory features differed between these inbred strains. Rag2(-/-); had blood pressure responses to pregnancy that did not differ from congenic normal mice. NOD.scid had higher midgestational blood pressure compared with normoglycemic NOD mice (3-5 mm Hg greater than NOD; P < 0.004). In comparison to controls, both T and B strains had much higher heart rates after first trimester that did not remit until parturition (>30 bpm greater than control; P < 0.0001). NOD.scid had additional anomalies, including 90% depletion of circulating NK cells and elevated (57%) proliferation of uterine NK cells within implantation sites. These data demonstrate immune control of midgestational heart rate and suggest NK cells contribute to midpregnancy regulation of mean arterial pressure.

Abstract
BACKGROUND Human uterine natural killer (uNK) cells, the dominant lymphocytes in early pregnancy decidua, are important for spiral arterial remodelling. uNK cells are thought to arise from circulating CD56(bright) NK cells that egress into decidualizing endometrium. Both incomplete spiral arterial modification and aberrant NK cell function have been linked with pre-eclampsia, a syndrome that is more prevalent in diabetic women. Since previous in vitro studies have shown that changes in decidual endothelium induced by type 1 diabetes (T1D) reduce its interactions with circulating leucocytes, we hypothesized that diabetes additionally has direct effects on circulating CD56(+) NK cells that impair their decidual homing potential. METHODS Serial blood samples were collected from control, T1D and T2D pregnant women throughout and after pregnancy. In vitro adhesion under shear forces was used to assay the functional capacity of circulating leucocytes and of CD56(+) cells to adhere to endothelium in cryostat sections of gestation day (gd) 7 normal mouse decidua, pancreas and lymph node. RESULTS Fewer CD56(+) cells from diabetic compared with control women adhered to normal decidual endothelium. The CD56(+) cell/total cell adhesion ratio was also lower in diabetics. More diabetic CD56(+) cells adhered to pancreatic endothelium and their proportion was greater than for controls. Neither absolute nor proportional adhesion of CD56(+) cells to lymph node endothelium differed between diabetics and controls. CONCLUSIONS The CD56(+) cell adhesion patterns of T1D and T2D women differ from those of non-diabetic women and support the hypothesis that diabetes impairs mechanisms that could be used by CD56(+) cells for egress into decidua.

Abstract
Viable human CD56+ CD16- peripheral blood Natural Killer (NK) cells show specific in vitro binding under shear forces to ligands expressed by endothelial cells in cryostat sections of gestation day (gd)7 mouse decidua basalis. In serial assays, numbers of cells adhering to gd7 tissue are constant for men but have cyclical variation for fertile women, suggesting a brief gain in functional decidual homing potential of this NK cell subset during the menstrual cycle. Regardless of gender, numbers of adhering cells from an individual donor, increase dramatically when the substrate is decidua basalis from a later gestational timepoint. Here, we report that human blood CD56+ CD16- NK cells which adhere as single cells over gd7 decidua basalis, adhere as large clusters over gd8 and gd9 tissues, suggestive of antigen recognition and lymphocyte activation. We asked which cells within mouse decidua basalis trigger this response in CD56+ CD16- cells. Using decidua from mice transgenic for myeloid dendritic cell (mDC) expression of enhanced yellow fluorescent protein (eYFP), we found cluster formation was independent of mDC contact. Use of decidua from alymphoid mice showed clustering behavior required substrate lymphocytes. By use of decidua containing NK cells but lacking T and B cells, decidual T and/or B lymphocytes were identified as the cells altered after gd7 in a manner that activates CD56+ CD16- cell clustering. This timepoint is just prior to mouse spiral arterial modification and its detection by these indicator cells implicates adaptive, decidual immune responses in the regulation of NK cell function.

Abstract
In some cases of infertility, implantation failure is due to a lack of expression of specific critical participating proteins such as cell adhesion molecules. The expression of beta 1 (beta1) integrin molecules within endometrial tissue has been proposed as a marker of uterine receptivity during the implantation window. Present study was conducted to assess uterine receptivity in women with unexplained infertility using beta1 integrin molecules within endometrial tissue in comparison with fertile women. This retrospective study was performed using a semiquantitative analysis on the immunohistochemical staining of beta1 integrins (VLA-4, VLA-5, VLA-6) in the mid-secretory phase of endometrium. Specimens were obtained from 30 fertile women and 28 infertile patients with a history of unexplained infertility. Chi-Square test was used to compare the expression and defect of beta1 integrin molecules between two groups. The results showed beta1 integrin molecules were present in fertile and infertile endometrial uterine tissues with different reactivity in different compartments. VLA-5 and VLA-6 expression on endometrial compartments showed an unrelated pattern of staining in either fertile or infertile women. The majority of glandular epithelial cells and stromal cells expressed VLA-4 integrin molecules in fertile endometrium. However, the reactivity with VLA-4 reduced significantly in both glandular epithelial cells and stromal cells in infertile women (p = 0.001). In conclusion differences may explain causes of unexplained infertility and suggests that VLA-4 integrin molecule may contribute in uterine endometrial receptivity at the time of the implantation window which requires more investigations in benign gynecologic diseases.

Abstract
Unique CD16(-) NK cells acutely increase in the human uterine endometrium after ovulation. The origin of these NK cells remains unknown, but they may be recruited selectively from the circulation. Proteoglycans and their glycosaminoglycan side-chains expressed on endometrial microvascular endothelial cells play a key role in lymphocyte tethering/rolling, the initial step of lymphocyte extravasation. In this study, we sought for the potential proteoglycans involved in tethering/rolling of peripheral blood CD16(-) NK cells on endometrial microvascular endothelial cells. As compared with CD16(+) NK cells and non-NK cells, enriched peripheral blood CD16(-) NK cells bound preferably to immobilized glycosaminoglycans except for keratan sulfate. CD16(-) NK cells bound maximally to dermatan sulfate (DS), which was diminished by enzymatic pretreatment with dermatanase and chondroitinase ABC, but not with chondroitinase ACII. The binding capacity of CD16(-) NK cells to DS was attenuated by blocking antibodies against selectin L and CD44 or pretreatment of CD16(-) NK cells with IL-15. Of three known DS proteoglycans, biglycan and decorin but not epiphycan were expressed in the human cycling endometrium. In the endometrial microvessels, the immunoreactivity for biglycan was greater in the secretory phase than in the proliferative phase, and there was little, if any, immunoreactivity for decorin throughout the menstrual cycle. The ovarian steroid progesterone enhanced biglycan expression in cultured human uterine microvascular endothelial cells. These findings demonstrated that DS proteoglycan biglycan is a potential selectin L/CD44 ligand involved in tethering/rolling of peripheral blood CD16(-) NK cells on endometrial microvascular endothelial cells.
