They break down and recycle old or damaged parts. We&#8217;ve known for a long time that the acid inside the lysosome is crucial for this process. But what scientists didn&#8217;t know is that a thin layer of acid also exists on the <em>outside<\/em> of the lysosome.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This discovery was made by a team of researchers who developed a new tool, a tiny &#8220;DNA nanodevice,&#8221; that can measure the pH level right on the surface of the lysosome in a living cell. Using this tool, they found a steady, acidic layer, just 21 nanometers thick, on the outer surface of every lysosome they examined.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This &#8220;acidic nanolayer&#8221; is more than just a curiosity; it plays a vital role in lysosomal function. The researchers found that it&#8217;s this outer layer of acid, not the acid inside, that controls how the lysosome moves around the cell.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">They also identified a specific protein that acts as a sensor for this outer acidic layer, helping to guide the lysosome&#8217;s movement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The implications of this discovery are huge. In models of Parkinson&#8217;s disease, the researchers found that the lysosomes had a significantly more acidic nanolayer, suggesting a potential link to the disease. The acidic layer also seems to play a role in how lysosomes interact with other parts of the cell.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This study has uncovered a whole new layer of complexity in how our cells work. By understanding this hidden acidic world, scientists may be able to develop new therapies for a wide range of diseases.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em><strong>Source: <\/strong><a href=\"https:\/\/www.nature.com\/articles\/s41556-025-01855-y\" data-type=\"link\" data-id=\"https:\/\/www.nature.com\/articles\/s41556-025-01855-y\" target=\"_blank\" rel=\"noopener\">Nature Cell Biology<\/a><\/em>\u00a0(2026).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Points Scientists in China have discovered a previously unknown &#8220;acidic nanolayer&#8221; that surrounds the recycling centers of our cells, a finding that could open&hellip;<\/p>\n","protected":false},"author":1,"featured_media":31038,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[50],"tags":[],"class_list":["post-31037","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-research"],"_links":{"self":[{"href":"https:\/\/techgolly.com\/news\/wp-json\/wp\/v2\/posts\/31037","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/techgolly.com\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/techgolly.com\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/techgolly.com\/news\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/techgolly.com\/news\/wp-json\/wp\/v2\/comments?post=31037"}],"version-history":[{"count":0,"href":"https:\/\/techgolly.com\/news\/wp-json\/wp\/v2\/posts\/31037\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/techgolly.com\/news\/wp-json\/wp\/v2\/media\/31038"}],"wp:attachment":[{"href":"https:\/\/techgolly.com\/news\/wp-json\/wp\/v2\/media?parent=31037"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/techgolly.com\/news\/wp-json\/wp\/v2\/categories?post=31037"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/techgolly.com\/news\/wp-json\/wp\/v2\/tags?post=31037"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
