A researcher investigates rheumatoid arthritis. If TNF-α secretion in the synovium is chronically elevated despite conventional treatment, which consequence is most likely?

💡 Explanation

Persistent TNF-α perpetuates inflammation via the NF-κB pathway, amplifying cytokine production and immune cell recruitment because TNF-α triggers further cytokine release. This unresolved positive feedback drives chronic inflammation, therefore the chronic inflammation persists rather than resolves due to immune regulation or reduced stimulation.

• If an axon terminal continuously releases acetylcholine but the postsynaptic receptors are dysfunctional, which consequence follows for muscle fiber contraction?
• Why does congenital hypothyroidism, if untreated, lead to intellectual disability?
• Why does post-inflammatory hyperpigmentation (PIH) persist longer in individuals with darker skin tones after cutaneous wound healing?
• If therapeutic ultrasound is applied to the brain of a patient with Alzheimer's disease, which consequence follows regarding amyloid-beta aggregates?
• Why does motor neuron axon demyelination cause muscle weakness?
• If a patient's distal convoluted tubule and collecting duct are impermeable to water due to non-functional aquaporins, which consequence follows regarding plasma osmolality and ADH levels?
