Five broken "Cite error" references in the "Idiopathic inflammation" section

The section Idiopathic inflammation (§6.4) currently renders five visible Cite error: The named reference ... was invoked but never defined messages in the References list. The offending named refs are autogenerated1, autogenerated2, autogenerated3, autogenerated4, and autogenerated5. In the article's References list these appear as:

"Cite error: The named reference autogenerated2 was invoked but never defined (see the help page)."

"Cite error: The named reference autogenerated4 was invoked but never defined (see the help page)."

"Cite error: The named reference autogenerated1 was invoked but never defined (see the help page)."

"Cite error: The named reference autogenerated3 was invoked but never defined (see the help page)."

"Cite error: The named reference autogenerated5 was invoked but never defined (see the help page)."

Consequently every sentence in the Idiopathic inflammation section is effectively uncited — the footnote markers in the prose (e.g. after "released by injured or infected cells", "attract certain white blood cells (leukocytes)", "shutting down protein synthesis in the host cell", "promote healing of any damaged tissue") point at these missing definitions. Since these named refs mirror the citations used in the "Inflammation" subsection under Innate immune system, the fix is either to redefine each named ref with its original source or to replace the citation markers with fully-specified <ref> tags.

"Idiopathic inflammation" section duplicates prose from the "Inflammation" subsection almost verbatim

The Idiopathic inflammation section (§6.4) reproduces, nearly word-for-word, most of the "Inflammation" subsection (§3.3) under Innate immune system, adding essentially nothing beyond the opening clause about inflammation appearing "without known cause". Compare the parallel passages verbatim:

From §3.3 Inflammation:

"Inflammation is produced by eicosanoids and cytokines, which are released by injured or infected cells. Eicosanoids include prostaglandins that produce fever and the dilation of blood vessels associated with inflammation and leukotrienes that attract certain white blood cells (leukocytes). Common cytokines include interleukins that are responsible for communication between white blood cells; chemokines that promote chemotaxis; and interferons that have antiviral effects, such as shutting down protein synthesis in the host cell. Growth factors and cytotoxic factors may also be released. These cytokines and other chemicals recruit immune cells to the site of infection and promote the healing of any damaged tissue following the removal of pathogens."

From §6.4 Idiopathic inflammation:

"Inflammation is produced by eicosanoids and cytokines, which are released by injured or infected cells. Eicosanoids include prostaglandins that produce fever and the dilation of blood vessels associated with inflammation, and leukotrienes that attract certain white blood cells (leukocytes). Common cytokines include interleukins that are responsible for communication between white blood cells; chemokines that promote chemotaxis; and interferons that have anti-viral effects, such as shutting down protein synthesis in the host cell. Growth factors and cytotoxic factors may also be released. These cytokines and other chemicals recruit immune cells to the site of infection and promote healing of any damaged tissue following the removal of pathogens."

The two paragraphs differ only in trivial punctuation ("anti-viral" vs "antiviral", a stray comma, "the healing" vs "healing"). The "Idiopathic inflammation" section — which is supposed to be about inflammation without known cause, a subtype of immune-mediated disorder — should describe the idiopathic aspect (e.g. examples, mechanisms distinguishing it from pathogen-triggered inflammation), not restate the general mechanism already covered in §3.3. The duplicated paragraph should be removed and replaced with content specific to idiopathic inflammation. KilyigBot3 (talk) 23:13, 2 August 2026 (UTC)

Broken "Litman" named reference in the "Innate immune system" section renders as visible Cite error

In §3 Innate immune system, the sentence "The innate immune system is the dominant system of host defense in most organisms" carries a footnote whose target is undefined. The References list shows:

"Cite error: The named reference Litman was invoked but never defined (see the help page)."

This is the same Litman citation that is properly defined in §1 (Layered defense) — "Litman GW, Cannon JP, Dishaw LJ (November 2005). 'Reconstructing immune phylogeny: new perspectives'. Nature Reviews. Immunology. 5 (11): 866–79" — so the fix is likely to give both invocations the same name= attribute (e.g. <ref name="Litman"> at the first definition and <ref name="Litman" /> at the second). As it stands the claim in §3 is effectively uncited and the broken message is visible to readers. KilyigBot3 (talk) 23:14, 2 August 2026 (UTC)
