Maximal Force Characteristics of the Ca[superscript 2+]-Powered Actuator of Vorticella convallaria by Ryu, Sangjin, Lang, Matthew J., Matsudaira, Paul T.

“…By applying viscous drag force to contracting V. convallaria in a microfluidic channel, we observed that the mechanical force and work of the spasmoneme depended on the stalk length, i.e., the maximum tension (150–350 nN) and work linearly depended on the stalk length (~2.5 nN and ~30 fJ per 1 μm of the stalk). …”

An Experimentally Tuned Dynamic Model Predicting Cell Migration for Guidance of Sprouting Endothelial Cells by Wood, Levi Benjamin, Asada, Haruhiko

“…The tuned model is used to evaluate the influence of different sprout elongation rates on cell density in the sprout stalk. This quantitative modeling approach will lead to input shaping and feedback control to optimize sprouting metrics such as stalk cell density. …”

Calcium-triggered fusion of lipid membranes is enabled by amphiphilic nanoparticles by Tahir, Mukarram A, Guven, Zekiye P., Arriaga, Laura R., Tinao, Berta, Yang, Yu-Sang Sabrina, Bekdemir, Ahmet, Martin, Jacob T, Bhanji, Alisha N., Irvine, Darrell J, Stellacci, Francesco, Alexander-Katz, Alfredo

“…While previous efforts to develop synthetic fusogens have only replicated the initial steps of the fusion cascade, we use molecular simulations and complementary experimental techniques to demonstrate that these nanoparticles can induce the formation of a lipid stalk and also drive its expansion into a fusion pore upon the addition of excess calcium. …”

Germline-Encoded Affinity for Cognate Antigen Enables Vaccine Amplification of a Human Broadly Neutralizing Response against Influenza Virus by Sangesland, Maya, Ronsard, Larance, Kazer, Samuel Weisgurt, Bals, Julia, Boyoglu-Barnum, Seyhan, Yousif, Ashraf S., Barnes, Ralston, Feldman, Jared, Quirindongo-Crespo, Maricel, McTamney, Patrick M., Rohrer, Daniel, Lonberg, Nils, Chackerian, Bryce, Graham, Barney S., Kanekiyo, Masaru, Shalek, Alexander K, Lingwood, Daniel

“…To test this, we generated transgenic mice with human CDRH3 diversity but simultaneously constrained to individual user-defined human immunoglobulin variable heavy-chain (VH) genes, including IGHV1-69, which shows biased usage in human bnAbs targeting the hemagglutinin stalk of group 1 influenza A viruses. Sequential immunization with a stalk-only hemagglutinin nanoparticle elicited group 1 bnAbs, but only in IGHV1-69 mice. …”

Three-Dimensional Characterization of Mechanical Interactions between Endothelial Cells and Extracellular Matrix during Angiogenic Sprouting by Du, Yue, Herath, Sahan C. B., Wang, Qing-guo, Wang, Dong-an, Chen, Peter C. Y., Asada, Haruhiko

“…We analyzed the data collected in-situ from angiogenic sprouting experiments and identified the differentiated interaction behavior exhibited by the tip and stalk cells. Moreover, our analysis of the tip cell lamellipodia revealed the diversity in their interaction behavior under certain conditions (e.g., when the heading of a sprout is switched approximately between the long-axis direction of two different lamellipodia). …”

Lipid tail protrusions mediate the insertion of nanoparticles into model cell membranes by Van Lehn, Reid C., Ricci, Maria, Silva, Paulo H.J., Andreozzi, Patrizia, Reguera, Javier, Voïtchovsky, Kislon, Stellacci, Francesco, Alexander-Katz, Alfredo

“…This last phenomenon is enhanced in the presence of high bilayer curvature and closely resembles the putative pre-stalk transition state for vesicle fusion. To the best of our knowledge, this work provides the first demonstration of vesicle fusion-like behaviour in an amphiphilic nanoparticle system.…”

Unsteady Motion, Finite Reynolds Numbers, and Wall Effect on Vorticella convallaria Contribute Contraction Force Greater than the Stokes Drag by Ryu, Sangjin, Matsudaira, Paul T.

“…Contraction of Vorticella convallaria, a sessile ciliated protozoan, is completed within a few milliseconds and results in a retraction of its cell body toward the substratum by coiling its stalk. Previous studies have modeled the cell body as a sphere and assumed a drag force that satisfies Stokes' law. …”
