Macrophages exposed continuously to lipopolysaccharide and other agonists that act via toll-like receptors exhibit a sustained and additive activation state [PDF]

, 2001
Background: Macrophages sense microorganisms through activation of members of the Toll-like receptor family, which initiate signals linked to transcription of many inflammation associated genes.

Biologic Functions and Signaling of the Interleukin-4 Receptor Complexes

Immunobiology, 2000
IL-4 is a pleiotropic cytokine which plays a pivotal role in shaping immune responses. The effects of IL-4 are mediated after binding to high affinity receptor complexes present on hematopoietic as well as non-hematopoietic cells. This review will summarize the current knowledge on the molecular structure of the different types of IL-4 receptor (IL-4R)

Short‐term response to biologic therapy in psoriatic arthritis (PsA) is not influenced by disease duration at initiation of therapy

Arthritis Care &Research, Accepted Article.
Objectives We aimed to determine whether the short‐term response to biologics in biologic‐naïve psoriatic arthritis (PsA) is better in patients initiating biologic treatment early in the disease course. Methods PsA patients who started biologic therapy from the year 2000 to 2025 were included for analysis. Patients considered in the early treatment (ET)

Purinergic receptors in skeletal muscles in health and in muscular dystrophy [PDF]

, 2014
The P2 purinergic (nucleotide) receptor super-family comprises of two families of protein. The P2X, which are channel-forming ionotropic receptors and the P2Y metabotropic receptors activating G protein-mediated signalling pathways.

Natriuretic peptide receptors on rat thymocytes: Inhibition of proliferation by atrial natriuretic peptide. [PDF]

, 1996
Because the thymus expresses the natriuretic peptides (NP) as well as their respective receptors, an involvement of NP in the physiology of this organ has been suggested.

Peculiarities of CD4+ cell signaling in asthma patients exposed to suspended solid particles of atmospheric air

Russian Open Medical Journal
Objective — To evaluate the expression of receptors for interleukin-4 (IL-4R), 6 (IL-6R), toll-like receptors 2 (TLR2) and 4 (TLR4) of T helper (Th) cells (CD4+), as well as the content of interleukin-4 (IL-4) and 6 (IL-6) in the blood serum of patients ...

Pull‐and‐Push Nanotherapeutic Hydrogels: Scavenging Inflammatory Triggers While Driving Tissue Regeneration in Burn Wounds

Advanced Functional Materials, EarlyView.
A nanounit‐assembled hydrogel employing a “pull‐and‐push” strategy simultaneously scavenges pro‐inflammatory cell‐free DNA (cfDNA) and delivers regenerative therapeutics in response to burn‐induced hyperthermia. By repolarizing macrophages and promoting angiogenesis, this multifunctional platform accelerates burn wound healing, offering a blueprint for

Novel mutations in the toll like receptor genes cause hyporesponsiveness to Mycobacterium avium subsp. paratuberculosis infection [PDF]

, 2008
Toll like receptors play a central role in the recognition of pathogen associated molecular patterns (PAMPs). Mutations in TLR1, TLR2 and TLR4 genes may change the PAMP reorganization ability which causes altered responsiveness to the bacterial pathogens.

Role of the chemokine receptors CCR1, CCR2 and CCR4 in the pathogenesis of experimental dengue infection in mice [PDF]

, 2010
Dengue virus (DENV), a mosquito-borne flavivirus, is a public health problem in many tropical countries. Recent clinical data have shown an association between levels of different chemokines in plasma and severity of dengue.

Gellan Gum Fluid Gel System for Controlled‐Delivery of Cytokine‐Licensed MSC‐EVs to Enhance Corneal Repair in Limbal Stem Cell Deficiency

Advanced Healthcare Materials, EarlyView.
Gellan gum fluid gel (FG) enables controlled ocular delivery of mesenchymal stromal cell (MSC)‐derived extracellular vesicles (EV). Its shear‐thinning, solid‐liquid‐solid rheology ensures prolonged ocular retention. Sustained MSC‐EV release (∼18% in 6 hrs) supports effective EV ocular delivery.
