Accuracy of direct gradient sensing by cell-surface receptors [PDF]

arXiv, 2009
Chemotactic cells of eukaryotic organisms are able to accurately sense shallow chemical concentration gradients using cell-surface receptors. This sensing ability is remarkable as cells must be able to spatially resolve small fractional differences in the numbers of particles randomly arriving at cell-surface receptors by diffusion.

A new theory of depression based on the serotonin/kynurenine relationship and the hypothalamicpituitary- adrenal axis

Biomédica: revista del Instituto Nacional de Salud, 2018
The serotonergic and immunological hypothesis of depression proposes that certain types of excessive stress distort the relationship between the activities of the innate immune and central nervous systems, so that the stress caused by an infection, or ...

Metabolic Consequences of Rheumatoid Arthritis

Arthritis Care &Research, EarlyView.
Patients with rheumatoid arthritis (RA) may have metabolic disruption, which can contribute to adverse long‐term outcomes, for multiple reasons. Patients with RA appear to have a higher risk of sarcopenia, type 1 and type 2 diabetes mellitus, metabolic syndrome, and hypertension. Systemic inflammation in RA can cause a “lipid paradox,” with reduced low‐

The Influence of IL-11 on Cardiac Fibrosis in Experimental Models: A Systematic Review

Journal of Cardiovascular Development and Disease
Fibrosis is one of the main factors that impair the function of many organs. In the heart, fibrosis leads to contractile dysfunction and arrhythmias, which are important in the development of heart failure.

Chemical sensing by cell-surface chemoreceptor arrays: the roles of receptor cooperativity and adaptation [PDF]

arXiv, 2012
Most sensory cells use cross-membrane chemoreceptors to detect chemical signals in the environment. The biochemical properties and spatial organization of chemoreceptors play important roles in achieving and maintaining sensitivity and accuracy of chemical sensing.

Time‐Controlled Dual Targeting to Program Systemic and Intercellular Transfer of Therapeutic Effects

Advanced Functional Materials, EarlyView.
Aspirin‐liposomes loaded onto monocytes enable inflammation‐triggered targeting and efficient hand‐over of aspirin to inflamed cells. Monocytes uptake a significant portion of aspirin‐liposomes, prolonging therapeutic action. This approach enhances anti‐inflammatory effects through intercellular transfer, demonstrating a translational strategy for ...

Engineering Novel DNA Nanoarchitectures for Targeted Drug Delivery and Aptamer Mediated Apoptosis in Cancer Therapeutics

Advanced Functional Materials, EarlyView.
Designer DNA Architecture‐templated Drug Conjugates (DDA‐DCs) are comprised of a DNA nanomaterial decorated with multiple drug‐loaded DNA aptamers. DDA‐DCs use a combination of multiple aptamer types, each recognizing a different membrane protein to achieve precise targeting of cancer cells.
