Signaling pathways for transduction of the initial message of the glycocode into cellular responses [PDF]
, 1998 The sugar units of glycan structures store information and establish an alphabet of life. The language of the oligosaccharide coding units is deciphered by receptors such as lectins and the decoded message can be transduced by multiple signaling pathways.

Astroglial calcium signaling displays short-term plasticity and adjusts synaptic efficacy
Frontiers in Cellular Neuroscience, 2015 Astrocytes are dynamic signaling brain elements able to sense neuronal inputs and to respond by complex calcium signals, which are thought to represent their excitability.

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Calcium signaling in lymphocytes [PDF]
Current Opinion in Immunology, 2008 In cells of the immune system, calcium signals are essential for diverse cellular functions including differentiation, effector function, and gene transcription. After the engagement of immunoreceptors such as T-cell and B-cell antigen receptors and the Fc receptors on mast cells and NK cells, the intracellular concentration of calcium ions is ...

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Gray matter NG2 cells display multiple Ca2+-signaling pathways and highly motile processes [PDF]
, 2011 NG2 cells, the fourth type of glia in the mammalian CNS, receive synaptic input from neurons. The function of this innervation is unknown yet. Postsynaptic changes in intracellular Ca2+-concentration ([Ca2+]i) might be a possible consequence. We employed

FEBS Letters, EarlyView.This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Calcium Signaling In Trypanosomatid Parasites
, 2016 Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Calcium ion (Ca2+) is an important second messenger in trypanosomatids and essential for their survival although prolonged high intracellular Ca2+ levels lead to cell death. As other eukaiyotic

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
