Ace is one of the young patients who Prof. Dr. Tilmann Kallinich from Charit\u00e9 \u2013 Universit\u00e4tsmedizin Berlin and the German Rheumatology Research Center Berlin (DRFZ), a Leibniz Institute, has been treating for five years. Together with PD Dr. Mir-Farzin Mashreghi, Deputy Scientific Director at DRFZ, he has uncovered the cellular and molecular mechanisms underlying this serious disease.\u00a0<\/p>\n\n\n\n<p class=\"alignwide has-text-align-wide wp-block-paragraph\">The article describes the story of six-year-old Ace Jaite, who in early 2022 suffered severely from inflammatory shock triggered by PIMS. PIMS occurs primarily as a result of COVID-19, causing children&#8217;s immune systems to overreact and attack organs such as the heart and kidneys. After several visits to the emergency room and a deterioration in his health, Ace was admitted to the intensive care unit at Charit\u00e9, where he was diagnosed in critical condition.<\/p>\n\n\n\n<p class=\"alignwide has-text-align-wide wp-block-paragraph\">Tilmann Kallinich, Professor of Pediatric Rheumatology at Charit\u00e9, recognized early on that this could be PIMS. However, the mechanism of the disease, which dysregulates the immune system and leads to multiple organ failure, was still largely unknown. Mir-Farzin Mashreghi works closely with Tilmann Kallinich and helped to identify specific markers that are characteristic of PIMS patients through cell analyses of the young patient. In particular, elevated TGF\u03b2 levels were identified as an indicator of the disease.<\/p>\n\n\n\n<p class=\"alignwide has-text-align-wide wp-block-paragraph\">PIMS is triggered by a dysregulated immune response in which the immune system attacks the body&#8217;s own organs. In severe cases, such as Ace&#8217;s, the disease leads to acute organ failure, which could only be treated with intensive medical care and early diagnosis. Thanks to the expertise of Kallinich and Mashreghi and targeted therapy, Ace was ultimately saved. Ace Jaite has now made a full recovery and has no long-term injuries from the disease.<\/p>\n\n\n\n<div class=\"wp-block-buttons alignwide is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/www.leibniz-magazin.de\/alle-artikel\/magazindetail\/newsdetails\/nach-dem-schock\">Leibniz article<\/a><\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading alignwide toc-item\" id=\"key-role-of-tgfss-and-ebv-in-pims\"><strong>Key role of TGF\u00df and EBV in PIMS<\/strong><\/h3>\n\n\n\n<p class=\"alignwide has-text-align-wide wp-block-paragraph\">In 2025, the underlying mechanism of the disease was published by Kallinich and Mashreghi in the journal Nature, representing an important scientific breakthrough. The authors discovered that the messenger substance TGF\u03b2 plays a crucial role in the dysregulation of the immune system. At the same time, the Epstein-Barr virus (EBV) is reactivated, leading to an extreme overreaction of the immune system and causing organ damage<\/p>\n\n\n\n<div class=\"wp-block-buttons alignwide is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/www.drfz.de\/en\/neuigkeiten\/ebv-reactivation-as-a-key-mechanism-of-mis-c-after-sars-cov-2-infection\/\">News about Nature publication<\/a><\/div>\n<\/div>\n\n\n\n  <section id=\"projektleiter\"    class=\"section grid-heads alignwide\">\n    <div class=\"container container--center\">\n              <div class=\"grid-heads__header\">\n                      <h2 class=\"section__heading launimation slideBottom\">Projektleiter<\/h2>\n          \n                  <\/div>\n      \n              <div class=\"grid-heads__items grid grid--4\">\n          \n<article\n  id=\"post-3991\" class=\"teaser-head launimation slideBottom  post-3991 head type-head status-publish has-post-thumbnail hentry department-pa-3-systems-rheumatology programme-area-function-leader programme-area-tax-programme-area-3 working-group-function-group-leader working-group-tax-therapeutic-gene-regulation\">\n  <div class=\"teaser-head__image\">\n          <img decoding=\"async\" loading=\"lazy\" sizes=\"auto, 520px\" src=\"https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/Mashreghi_Mir-Farzin-150x100.jpg\" data-src=\"https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/Mashreghi_Mir-Farzin-1024x684.jpg\" data-srcset=\"https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/Mashreghi_Mir-Farzin-1920x1282.jpg 1920w, https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/Mashreghi_Mir-Farzin-1600x1068.jpg 1600w, https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/Mashreghi_Mir-Farzin-1366x912.jpg 1366w, https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/Mashreghi_Mir-Farzin-1024x684.jpg 1024w, https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/Mashreghi_Mir-Farzin-768x513.jpg 768w, https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/Mashreghi_Mir-Farzin-550x367.jpg 550w\" class=\"image image--landscape\" alt=\"\"  width=\"1024\"  height=\"684\">      <\/div>\n  <div class=\"teaser-head__header\">\n    <!--    -->    <!--      -->    <!--    -->    <h2 class=\"h6 teaser-head__title launimation slideBottom\">Dr. Mir-Farzin Mashreghi<\/h2>\n          <div class=\"teaser-head__role\">\n                          <p class=\"text-label programme_area_function programme_area department\">\n            Leader: Programme Area 3, PA 3 \u2013 Systems Rheumatology          <\/p>\n                          <p class=\"text-label working_group_function working_group\">\n            Group leader: Therapeutic Gene Regulation          <\/p>\n                      <\/div>\n      <\/div>\n\n      <div class=\"teaser-head__contact\">\n              <p class=\"text-label\"><a href=\"mailto:mashreghi@drfz.de\"\">mashreghi@drfz.de<\/a><\/p>\n          <\/div>\n    <a href=\"https:\/\/www.drfz.de\/en\/koepfe\/mir-farzin-mashreghi\/\"\n    aria-describedby=\"post-3991\"\n    title=\"Gehe zum Beitrag\" rel=\"bookmark\"\n    class=\"teaser-head__link button button--small button--arrow button--arrow-link\"><span\n      class=\"visually-hidden\">Dr. Mir-Farzin Mashreghi<\/span><\/a>\n<\/article>\n<article\n  id=\"post-4005\" class=\"teaser-head launimation slideBottom  post-4005 head type-head status-publish has-post-thumbnail hentry department-pa-3-systems-rheumatology liaison-charite-dep-of-pediatric-respiratory-medicine-immunology-and-critical-care-medicine programme-area-tax-programme-area-3 working-group-function-group-leader working-group-tax-chronic-inflammation-in-childhood\">\n  <div class=\"teaser-head__image\">\n          <img decoding=\"async\" loading=\"lazy\" sizes=\"auto, 520px\" src=\"https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/Kallinich_Tillmann-150x100.jpg\" data-src=\"https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/Kallinich_Tillmann-1024x682.jpg\" data-srcset=\"https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/Kallinich_Tillmann-1920x1280.jpg 1920w, https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/Kallinich_Tillmann-1600x1066.jpg 1600w, https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/Kallinich_Tillmann-1366x910.jpg 1366w, https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/Kallinich_Tillmann-1024x682.jpg 1024w, https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/Kallinich_Tillmann-768x512.jpg 768w, https:\/\/www.drfz.de\/wp-content\/uploads\/2024\/12\/Kallinich_Tillmann-550x367.jpg 550w\" class=\"image image--landscape\" alt=\"\"  width=\"1024\"  height=\"682\">      <\/div>\n  <div class=\"teaser-head__header\">\n    <!--    -->    <!--      -->    <!--    -->    <h2 class=\"h6 teaser-head__title launimation slideBottom\">Prof. Dr. med.
