The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

open access: yesThe Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

“Visiting scientist effect”? Exploring the impact of time‐lags in the digitization of 2D landmark data

open access: yesThe Anatomical Record, EarlyView.
Abstract Measurement error (ME) in geometric morphometrics has been the subject of countless articles, but none specific to the effect of time lags on landmark digitization error. Yet, especially for visiting scientists working on museum collections, it is not uncommon to collect data in multiple rounds, with interruptions of weeks or years. To explore

Molecular mimicry or structural mimicry?

Molecular Immunology, 2006
"Molecular mimicry" should be changed to "structural mimicry". The immune system recognizes shapes--three-dimensional shapes--not sequences. For two sequences to act biologically similar they must possess similar three-dimensional structures.

Molecular mimicry and auto-immunity

Clinical Reviews in Allergy & Immunology, 2007
The term "molecular mimicry" was coined by R. Damian in 1964, who was first to suggest that antigenic determinants of micro-organisms may resemble antigenic determinants of their host. Damian suggested that this similarity served as a defense mechanism of a microorganism from the host's immune system and prevented the development of immune response to ...

Chemokine receptors and molecular mimicry

Immunology Today, 1994
Chemokines are small pro-inflammatory peptides that are best known for their leukocyte-chemoattractant activity. The cloned leukocyte chemokine receptors, interleukin 8 receptor (IL-8R) types A and B and the macrophage inflammatory protein 1 alpha (MIP-1 alpha)/RANTES receptor, are related by sequence and chemokine binding to two herpesvirus products ...

Molecular mimicry revisited

Parasitology Today, 1987
The host immune response is an important line of defence against parasites. Tactics to evade this response are therefore expected in host-parasite relationships, and the clearest example is the antigenic variation displayed by African trypanosomes. But while few other parasites seem to have quite this ability, many seem to display a form of antigenic ...

Molecular Mimicry in Multiple Sclerosis

New England Journal of Medicine, 2003
Molecular mimicry is a model in which foreign antigens are sufficiently similar to native antigens to trigger an autoimmune response. A study involving the specificity of a T-cell receptor derived from a patient with multiple sclerosis indicates that molecular mimicry extends to complexes of proteins — a finding with implications for therapy.
