![]() ![]() The W3C also encourages use of the most current version of WCAG when developing or updating Web accessibility policies. While WCAG 2.0 remains a W3C Recommendation, the W3C advises the use of WCAG 2.1 to maximize future applicability of accessibility efforts. ![]() The publication of WCAG 2.1 does not deprecate or supersede WCAG 2.0. The WG intends that for policies requiring conformance to WCAG 2.0, WCAG 2.1 can provide an alternate means of conformance. Content that conforms to WCAG 2.1 also conforms to WCAG 2.0. ![]() WCAG 2.1 extends Web Content Accessibility Guidelines 2.0, which was published as a W3C Recommendation December 2008. See Web Content Accessibility Guidelines (WCAG) Overview for an introduction and links to WCAG technical and educational material. Guidance about satisfying the success criteria in specific technologies, as well as general information about interpreting the success criteria, is provided in separate documents. WCAG 2.1 success criteria are written as testable statements that are not technology-specific. Following these guidelines will also often make Web content more usable to users in general. These guidelines address accessibility of web content on desktops, laptops, tablets, and mobile devices. Following these guidelines will make content more accessible to a wider range of people with disabilities, including accommodations for blindness and low vision, deafness and hearing loss, limited movement, speech disabilities, photosensitivity, and combinations of these, and some accommodation for learning disabilities and cognitive limitations but will not address every user need for people with these disabilities. Web Content Accessibility Guidelines (WCAG) 2.1 covers a wide range of recommendations for making Web content more accessible. ![]() This document is also available in non-normative formats, available from Alternate Versions of Web Content Accessibility Guidelines 2.1. Please check the errata for any errors or issues We show that EC cells express specific chemosensory receptors, are electrically excitable, and modulate serotonin-sensitive primary afferent nerve fibers via synaptic connections, enabling them to detect and transduce environmental, metabolic, and homeostatic information from the gut directly to the nervous system.Web Content Accessibility Guidelines (WCAG) 2.1 W3C Recommendation 05 June 2018 This version: Latest published version: Latest editor's draft: Implementation report: Previous version: Previous Recommendation: Editors: Andrew Kirkpatrick (Adobe) Joshue O Connor (Invited Expert, InterAccess) Alastair Campbell (Nomensa) Michael Cooper ( W3C) WCAG 2.0 Editors (until December 2008): Ben Caldwell (Trace R&D Center, University of Wisconsin-Madison) Loretta Guarino Reid (Google, Inc.) Gregg Vanderheiden (Trace R&D Center, University of Wisconsin-Madison) Wendy Chisholm ( W3C) John Slatin (Accessibility Institute, University of Texas at Austin) Jason White (University of Melbourne) Here, we circumvent this limitation by exploiting cultured intestinal organoids together with single-cell measurements to elucidate intrinsic biophysical, pharmacological, and genetic properties of EC cells. Serotonergic enterochromaffin (EC) cells are proposed to fulfill this role by acting as chemosensors, but understanding how these rare and unique cell types transduce chemosensory information to the nervous system has been hampered by their paucity and inaccessibility to single-cell measurements. The gut epithelium is a principal site for detecting such agents, but precisely how it communicates with neural elements is poorly understood. Dietary, microbial, and inflammatory factors modulate the gut-brain axis and influence physiological processes ranging from metabolism to cognition. ![]()
