Fundamental constraints on the abundances of chemotaxis proteins [PDF]

open access: yesBiophys. J. 108(5): 1293-1305 (2015), 2015
Flagellated bacteria, such as Escherichia coli, perform directed motion in gradients of concentration of attractants and repellents in a process called chemotaxis. The E. coli chemotaxis signaling pathway is a model for signal transduction, but it has unique features.

The transducer-like protein Tlp12 of Campylobacter jejuni is involved in glutamate and pyruvate chemotaxis

open access: yesBMC Microbiology, 2018
Background Campylobacter jejuni is one of the most common bacterial causes of food-borne enteritis worldwide. Chemotaxis in C. jejuni is known to be critical for the successful colonization of the host and key for the adaptation of the microbial species ...

Adaptation dynamics in densely clustered chemoreceptors [PDF]

open access: yes, 2013
In many sensory systems, transmembrane receptors are spatially organized in large clusters. Such arrangement may facilitate signal amplification and the integration of multiple stimuli. However, this organization likely also affects the kinetics of signaling since the cytoplasmic enzymes that modulate the activity of the receptors must localize to the ...

Autonomous Navigation of Bio‐Intelligent Cyborg Insect Based on Insect Visual Perception

open access: yesAdvanced Intelligent Systems, EarlyView.
The bio‐intelligent cyborg insect (BCI) introduces a noninvasive ultraviolet‐based control method, leveraging natural sensory behaviors for adaptive navigation. By integrating biological and artificial intelligence, BCI minimizes habituation and enhances locomotion in complex environments.

Unusual Manifestations after a Case of Carotid Body Tumour Excision: A Case Report [PDF]

open access: yesJournal of Krishna Institute of Medical Sciences University, 2018
Carotid body tumours are rare tumours arising from chemoreceptor cells at the bifurcation of carotid artery. They are highly vascular and mostly benign but with potential to turn into malignancy.

Chronic exposure to perfluorooctane sulfonate induces behavior defects and neurotoxicity through oxidative damages, in vivo and in vitro. [PDF]

open access: yesPLoS ONE, 2014
Perfluorooctane sulfonate (PFOS) is an emerging persistent pollutant which shows multiple adverse health effects. However, the neurotoxicity of PFOS and its mechanisms have not been fully elucidated.

Muffled olfactory and sensory cues from the reproductive stage soybean selectively reduce oviposition of a major polyphagous herbivore, fall armyworm (Spodoptera frugiperda)

open access: yesPest Management Science, EarlyView.
Fall armyworm (FAW) preferred ovipositing on vegetative‐stage soybeans. While ‘mother knows best’ may not apply in soybean‐FAW system, muffled cues in the reproductive stage could positively influence host success. Abstract BACKGROUND While the mother knows best/preference performance hypothesis has been well tested in natural ecosystems, how these ...

KISS1 and KISS1R expression in the human and rat carotid body and superior cervical ganglion [PDF]

open access: yes, 2011
KISS1 and its receptor, KISS1R, have both been found to be expressed in central nervous system, but few data are present in the literature about their distribution in peripheral nervous structures.

A Mathematical Description of Bacterial Chemotaxis in Response to Two Stimuli [PDF]

open access: yesarXiv, 2020
Bacteria are often exposed to multiple stimuli in complex environments, and their efficient chemotactic decisions are critical to survive and grow in their native environments. Bacterial responses to the environmental stimuli depend on the ratio of their corresponding chemoreceptors.
