"content": "\"Mini-organ\" boosts immune responses: so called tertiary lymphoid structures (TLS) are catalysators of the immune system. These round structures have an inner core of antigen-presenting cells and a broader rim of effector T cells. The presence of TLS is associated with treatment response to <a href=\"https://pixelfed.social/discover/tags/immunotherapy?src=hash\" title=\"#immunotherapy\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#immunotherapy</a> in various cancers (e.g. <a href=\"https://pixelfed.social/discover/tags/sarcoma?src=hash\" title=\"#sarcoma\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#sarcoma</a>, <a href=\"https://pixelfed.social/discover/tags/melanoma?src=hash\" title=\"#melanoma\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#melanoma</a>, <a href=\"https://pixelfed.social/discover/tags/lungcancer?src=hash\" title=\"#lungcancer\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#lungcancer</a>). But what triggers their existence? And: how can the neo-formation of TLS be triggered in cancer patients? Inducing TLS formation could be an exciting new avenue for immunotherpies, read more in our article here:<br />\n<br />\n<a href=\"https://www.nature.com/articles/s41392-025-02260-5\" rel=\"external nofollow noopener\">https://www.nature.com/articles/s41392-025-02260-5</a><br />\n<br />\n<a href=\"https://pixelfed.social/discover/tags/science?src=hash\" title=\"#science\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#science</a> <a href=\"https://pixelfed.social/discover/tags/Oncology?src=hash\" title=\"#Oncology\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#Oncology</a> <a href=\"https://pixelfed.social/discover/tags/immunology?src=hash\" title=\"#immunology\" class=\"u-url hashtag\" rel=\"external nofollow noopener\">#immunology</a>",
