Memory T helper (Th) cells sustain protective recall responses but can also drive chronic inflammation, necessitating precise regulation of their effector programs. Although Th cells produce acetylcholine (ACh) and express nicotinic acetylcholine receptors (nAChRs), the contribution of nAChRs to ...

Introduction: Cancers often drive T cells toward an exhausted state characterized by impaired cytotoxicity and upregulation of inhibitory receptors (PD-1, TIM-3, CD38) and transcriptional regulators (TOX, NFATc1). Repeated stimulation in vitro is used to model this process, reflecting chronic antigen exposure in the tumor microenvironment. Stress-derived ...

Memory T helper (Th) cells, generated in response to immunogenic challenges, are crucial in orchestrating adaptive immune responses. Acetylcholine (ACh), a key neurotransmitter of the parasympathetic nervous system, modulates immune function via muscarinic ACh receptors (mAChRs). This study inves ...

Genetically engineering human immune cells has been shown to be an effective approach for developing novel cellular therapies to treat a wide range of diseases. To expand the scope of these cellular therapies while solving persistent challenges, extensive research and development is still require ...

While met with initial and ground-breaking success targeting blood borne cancers, cellular immunotherapy remains significantly hindered in the context of solid tumors by the tumor microenvironment. Focused ultrasound, in conjunction with microbubbles, has found tremendous potential as a targeted and local drug/gene delivery technique for cancer therapy. T ...

Introduction: Adrenergic receptors regulate metabolic, cardiovascular, and immunological functions in response to the sympathetic nervous system. The effect of ß2-adrenergic receptor (AR) as a high expression receptor on different subpopulations of T cells is complex and varies depending on the t ...

Background: T helper 17 (Th17) cells produce IL-17A cytokine and can exacerbate autoimmune diseases and asthma. The ß2 adrenergic receptor is a g protein-coupled receptor that induces cAMP second messenger pathways. We tested the hypothesis that terbutaline, a ß2-adrenergic receptor-specific agon ...

Candida albicans, an important fungal pathogen of humans, displays different morphologies, such as yeast, pseudo-hyphae and hyphae, which are recognized unequally by phagocytic cells of the innate immune response. Once C. albicans cells invade host tissues, immune cells such as macrophages are attracted to the site of infection and activated to recognize, ...

To understand the variable response to pain, researchers have examined the change in cardiovascular measures to a uniform painful stimulation. Pain catastrophizing is the tendency to magnify or exaggerate pain sensations, and it affects the outcome of rehabilitation in a clinical setting. Its eff ...

Context: Athletes are often exposed to pain due to injury and competition. Using preliminary evidence, researchers have shown that cardiovascular measures could be an objective measure of pain, but the cardiovascular response can be influenced by psychological factors, such as catastrophizing. Objective: To use a painful cold-pressor test (CPT) to measur ...
