Brazilian Journal of Medical and Biological Research, 2005 Viruses share antigenic sites with normal host cell components, a phenomenon known as molecular mimicry. It has long been suggested that viral infections might trigger an autoimmune response by several mechanisms including molecular mimicry.

An introgressed wing pattern acts as a mating cue. [PDF]
, 2015 Heliconius butterflies provide good examples of both homoploid hybrid speciation and ecological speciation. In particular, examples of adaptive introgression have been detected among the subspecies of Heliconius timareta, which acquired red color pattern

A possible role for autoimmunity through molecular mimicry in alphavirus mediated arthritis
Scientific Reports, 2020 Alphaviral infections are foremost in causing debilitating clinical outcomes in humans characterized by rheumatic arthritis like conditions. Though the presence of virus in joints and associated inflammation has been implicated as one of the reasons for ...

An evolutionary approach to Function [PDF]
, 2009 The distinction between function and role is a vexed and difficult one. While the distinction appears to be useful, in practice it is hard to apply; this can be even worse when applying this distinction to biology.

Rat models of autoimmune uveitis [PDF]
, 2008 Experimental autoimmune uveitis ( EAU) in Lewis rats is a well-established model for human uveitis. During the last years we used this model to demonstrate extraocular induction of uveitis by antigenic mimicry of environmental antigens with retinal ...

Evolutionary interplay between viruses and R‐loops
FEBS Letters, EarlyView.Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Müllerian mimicry as a result of codivergence between velvet ants and spider wasps.
PLoS ONE, 2014 Recent studies have delineated a large Nearctic Müllerian mimicry complex in Dasymutilla velvet ants. Psorthaspis spider wasps live in areas where this mimicry complex is found and are phenotypically similar to Dasymutilla.

FEBS Letters, EarlyView.Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

Epitopedia: identifying molecular mimicry between pathogens and known immune epitopes
ImmunoInformatics, 2023 Upon infection, foreign antigenic proteins stimulate the host's immune system to produce antibodies targeting the pathogen. These antibodies bind to regions on the antigen called epitopes.

Drosophila as a model system to study nonautonomous mechanisms affecting tumour growth and cell death [PDF]
, 2018 The study of cancer has represented a central focus in medical research for over a century. The great complexity and constant evolution of the pathology require the use of multiple research model systems and interdisciplinary approaches.
