Maternal Serum Cytokine Concentrations in Healthy Pregnancy and Preeclampsia
Journal of Pregnancy, 2021 The maternal immune response is essential for successful pregnancy, promoting immune tolerance to the fetus while maintaining innate and adaptive immunity. Uncontrolled, increased proinflammatory responses are a contributing factor to the pathogenesis of

Niche Occupation Limits Adaptive Radiation in Experimental Microcosms [PDF]
, 2007 Adaptive radiations have played a key role in the evolution of biological diversity. The breadth of adaptive radiation in an invading lineage is likely to be influenced by the availability of ecological niches, which will be determined to some extent by ...

Cell Stem Cell, 2008 Notch signaling is essential for hematopoietic stem cell (HSC) formation during embryogenesis, and hitherto it was also thought to be required for HSC maintenance. However, in this issue of Cell Stem Cell, Maillard et al. (2008) demonstrate rather conclusively that inactivation of the Notch pathway in HSCs does not interfere with their self-renewal.

La niche écologique, mythe ou réalité ? [PDF]
, 1979 The niche concept in ecology can be approached either empi rically or theoretically. The emphasis is laid in this paper on the empirical approach, and the authors make use of their per- sonnal field experience to illustrate the points discussed.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Cell Stem Cell, 2008 SummaryA trio of studies in this issue of Cell Stem Cell from Mirzadeh et al., Shen et al., and Tavazoie et al. use three-dimensional imaging techniques to reveal microanatomical details of the adult neural stem cell niche. Combined, the results also provide a framework for future functional studies.

The human gut microbiome across the life course
FEBS Letters, EarlyView.Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Investigation of the heterogeneity of cancer cells using single cell Ca2+ profiling
Cell Communication and SignalingBackground Calcium (Ca2+) is an essential second messenger that controls numerous cellular functions. Characteristics of intracellular Ca2+ oscillations define Ca2+ signatures representatives of the phenotype of a cell.
