Abstract

A new neutrophil-activating peptide, termed ENA-78, was identified in the conditioned media of stimulated human type II epithelial cell line A549. In response to stimulation with either interleukin 1 beta (IL-1 beta) or tumor necrosis factor alpha (TNF-alpha), ENA-78 was produced and secreted concomitantly with IL-8, GRO alpha, and GRO gamma. ENA-78 consists of 78 amino acids [sequence; see text] and has a molecular weight of 8,357. It has four cysteines positioned identically to those of IL-8 and analogues, and thus belongs to the CXC family of peptides. ENA-78 is related to neutrophil-activating peptide 2 (NAP-2) and GRO alpha (sequence identity, 53% and 52%, respectively) and IL-8 (22% identity). Like NAP-2 and GRO alpha, ENA-78 stimulates neutrophils, inducing chemotaxis, a rise in intracellular free calcium and exocytosis. Cross-desensitization experiments indicate that ENA-78 acts through the same type of receptors as IL-8, NAP-2, and GRO alpha.

  • LIX/ENA-78 levels are present at normal levels in THS-exposed mouse wounds.

    “Although the levels of KC, chemoattractant for neutrophils [57,58], were reduced in the THS-exposed mouse wounds the levels of LIX/ENA-78, another chemokine that chemoattracts neutrophils was present at normal levels [59].”

    From Tobacco toxins deposited on surfaces (third hand smoke) impair wound healing (2016) · cites this paper as [59]

    The Biological Activities results (p. 1358, Fig. 6) show that ENA-78 induces human neutrophil migration, supporting its description as a neutrophil chemoattractant. The paper studies human cells, not THS-exposed mouse wounds, and does not establish that LIX/ENA-78 was present at normal levels in those wounds. (LLM, conf=0.87)

    The Results (Fig. 6; page not provided) show that ENA-78 induces human neutrophil migration, which relates to the sentence’s later citation [59]. Our copy does not address KC levels in THS-exposed mouse wounds; searches for KC, THS, and mouse wounds found no relevant passage. (LLM, conf=0.78)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
