Mechanisms of cAMP compartmentation in cardiac myocytes: experimental and computational approaches to understanding [PDF]

, 2021
The small diffusible second messenger 3’,5’-cyclic adenosine monophosphate (cAMP) is found in virtually every cell in our bodies, where it mediates responses to a variety of different G protein coupled receptors (GPCRs).

Regulatory T-cell compartmentalization and trafficking

Blood, 2006
CD4+CD25+FOXP3+ regulatory T cells (CD4+ Treg cells) are thought to differentiate in the thymus and immigrate from the thymus to the periphery. Treg cells can regulate both acquired and innate immunity through multiple modes of suppression. The cross-talk between Treg cells and targeted cells, such as antigen-presenting cells (APCs) and T cells, is ...

CD95 co-stimulation blocks activation of naive T cells by inhibiting T cell receptor signaling [PDF]

, 2009
CD95 is a multifunctional receptor that induces cell death or proliferation depending on the signal, cell type, and cellular context. Here, we describe a thus far unknown function of CD95 as a silencer of T cell activation.

Plant cell wall lignification and monolignol metabolism

Frontiers in Plant Science, 2013
Plants are built of various specialized cell types that differ in their cell wall composition and structure. The cell walls of certain tissues (xylem, sclerenchyma) are characterized by the presence of the heterogenous polymer lignin that plays an ...

Non-structural Carbohydrate Metabolism in the Flesh of Stone Fruits of the Genus Prunus (Rosaceae) – A Review

Frontiers in Plant Science, 2020
Non-structural carbohydrates are abundant constituents of the ripe flesh of all stone fruits. The bulk of their content comprises sucrose, glucose, fructose and sorbitol.

G1 Compartmentalization and Cell Fate Coordination [PDF]

Cell, 2013
Pauklin and Vallier show that, whereas early G1 is permissive for TGF-β-dependent endoderm differentiation, cyclin D restricts the activity of Smad2/3 in late G1, resulting in a switch from endoderm to neuroectoderm potential in pluripotent stem cells.

Subcellular compartmentation of sugar signalling: Links among carbon cellular status, route of sucrolysis, sink-source allocation, and metabolic partitioning

Frontiers in Plant Science, 2013
Recent findings suggest that both subcellular compartmentation and route of sucrolysis are important for plant development, growth, and yield. Signalling effects are dependent on the tissue, cell type and stage of development.

Combinatorial guidance by CCR7 ligands for T lymphocytes migration in co-existing chemokine fields. [PDF]

PLoS ONE, 2011
Chemokines mediate the trafficking and positioning of lymphocytes in lymphoid tissues that is crucial for immune surveillance and immune responses. In particular, a CCR7 ligand, CCL21, plays important roles in recruiting T cells to secondary lymphoid ...

Crosstalk Between LXR and Caveolin-1 Signaling Supports Cholesterol Efflux and Anti-Inflammatory Pathways in Macrophages

Frontiers in Endocrinology, 2021
Macrophages are immune cells that play crucial roles in host defense against pathogens by triggering their exceptional phagocytic and inflammatory functions.

Compartmentation of photosynthesis in cells and tissues of C4 plants [PDF]

Journal of Experimental Botany, 2001
Critical to defining photosynthesis in C(4) plants is understanding the intercellular and intracellular compartmentation of enzymes between mesophyll and bundle sheath cells in the leaf. This includes enzymes of the C(4) cycle (including three subtypes), the C(3) pathway and photorespiration. The current state of knowledge of this compartmentation is a
