Inflammatory cells and bone loss in rheumatoid arthritis
Arthritis Research & Therapy
|July 3, 2007
Summary
Inflammation causes bone erosion, particularly in rheumatoid arthritis. Neutrophils, inflammatory cells in rheumatoid joints, express factors that regulate this bone erosion.
Area of Science:
- Immunology
- Rheumatology
- Cell Biology
Background:
- Pathogenic bone erosion is frequently linked to inflammatory processes.
- Rheumatoid arthritis is characterized by destructive bone erosion, likely due to inflamed tissues near bone.
Discussion:
- Recent research has significantly advanced the understanding of factors regulating osteoclast bone resorption.
- These regulatory factors are notably expressed by inflammatory cells within the rheumatoid joint.
Key Insights:
- Neutrophils are identified as inflammatory cells present in inflamed rheumatoid joints.
- Neutrophils express factors that play a role in regulating bone erosion.
Outlook:
- Further investigation into neutrophil-derived factors could reveal new therapeutic targets for inflammatory bone diseases.
- Understanding the interplay between neutrophils and bone resorption may lead to novel treatment strategies for rheumatoid arthritis.

T Cell Types and Functions
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

Osteoclasts in Bone Remodeling
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
