Microfluidic flow chambers etched by photolithography and fabricated from PDMS are applied to probe functional outcomes associated with EC dysfunction and inflammation. In a representative experiment, the ability of differential shear stress to modulate monocytic cell adhesion to cytokine activated EC monolayers is demonstrated.

Intrinsically Disordered Proteins

2020
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Inflammatory Response

2024
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function. Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

2023
Recently, it has been discovered that behavioral conditions such as, depression, anxiety and stress-response have a neurological basis. Understanding the biological underpinnings of these conditions may help scientists in developing more effective therapies to treat these disorders. Typically, rodent models are used in this field and behavioral scientists create these models using interventions like drug administration or surgery. It is important to understand how to create and evaluate rodent...

Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California Attention, working-memory, planning, impulse control, inhibition, and mental flexibility are important components of human cognition that are often referred to as executive functions. Autism spectrum disorder is a developmental disorder that is characterized by impairments in social interaction, communication, and repetitive behaviors. It is a disorder that lasts a lifetime, and is thought to affect...
FAQs
The process begins when immune cells detect injury, infection, or abnormal signals. They then release signaling molecules that change local blood flow, attract additional immune cells, and activate tissue repair. In inflammatory disorders, this coordinated response can become excessive, prolonged, or misdirected, shifting inflammation from a protective reaction toward disruption of normal tissue function.
These mediators coordinate different parts of the inflammatory response. Cytokines and chemokines support communication among immune cells and help recruit additional cells, while prostaglandins contribute to changes in blood flow. Together, their signals connect immune recognition with cellular recruitment and tissue repair, making their regulation important for limiting harmful inflammation.
Inflammatory signaling is beneficial when it responds appropriately to a problem and supports repair. If the signals continue, however, immune activity and repair-related changes may persist after normal tissue regulation is disrupted. Chronic inflammation can then damage tissue rather than restore it, illustrating why balanced signaling is essential for maintaining tissue homeostasis.
A regulated response coordinates immune recognition, mediator release, recruitment of cells, and tissue repair in a way that supports recovery. In inflammatory disorders, the response may be excessive, prolonged, or misdirected. The key distinction is not simply whether inflammation occurs, but whether immune signaling remains appropriately controlled while protective host defenses and normal tissue function are preserved.
Researchers can examine how immune regulation, cellular communication, and tissue homeostasis interact. This includes considering how immune cells recognize signals, how mediators alter blood flow and recruit cells, and how repair responses affect tissue function. Studying these connected processes helps explain why inflammation becomes persistent and identifies points where harmful activity might be controlled.
Research can connect abnormal immune signaling and tissue disruption with measurable biological indicators. By examining mediators such as cytokines, chemokines, and prostaglandins alongside changes in tissue function, investigators can identify candidate diagnostic biomarkers. These markers may help characterize inflammatory activity and support efforts to distinguish harmful, persistent responses from appropriately regulated immune protection.
The central goal is to reduce harmful inflammation without eliminating protective host defenses. This requires understanding which immune signals are excessive, prolonged, or misdirected and how they affect tissue repair and homeostasis. Biological knowledge of these relationships supports treatment development aimed at restoring balance rather than broadly suppressing every component of the immune response.
