During phagocytosis, pathogens are internalized and degraded in phagolysosomes. For pathogens that evade immune degradation, the prevailing view is that virulence factors are required to disrupt the biogenesis of phagolysosomes. In contrast, we present here that physical forces from motile pathogens during cell entry divert them away from the canonical degradative pathway. This altered fate begins with the force-induced remodeling of the phagocytic synapse formation. We used the parasite\n                    <jats:italic>Toxoplasma gondii<\/jats:italic>\n                    as a model because live\n                    <jats:italic>Toxoplasma<\/jats:italic>\n                    actively invades host cells using gliding motility. To differentiate the effects of physical forces from virulence factors in phagocytosis, we employed magnetic forces to induce propulsive entry of inactivated\n                    <jats:italic>Toxoplasma<\/jats:italic>\n                    into macrophages. Experiments and computer simulations show that large propulsive forces hinder productive activation of receptors by preventing their spatial segregation from phosphatases at the phagocytic synapse. Consequently, the inactivated parasites are engulfed into vacuoles that fail to mature into degradative units, similar to the live motile parasite\u2019s intracellular pathway. Using yeast cells and opsonized beads, we confirmed that this mechanism is general, not specific to the parasite used. These results reveal new aspects of immune evasion by demonstrating how physical forces during active cell entry, independent of virulence factors, enable pathogens to circumvent phagolysosomal degradation.\n                  <\/jats:p>","DOI":"10.1073\/pnas.2306788120","type":"journal-article","created":{"date-parts":[[2023,11,30]],"date-time":"2023-11-30T13:37:18Z","timestamp":1701351438000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":7,"title":["Propulsive cell entry diverts pathogens from immune degradation by remodeling the phagocytic synapse"],"prefix":"10.1073","volume":"120","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6667-1200","authenticated-orcid":false,"given":"Zihan","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Chemistry, Indiana University, Bloomington, IN 47405-7102"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6585-3595","authenticated-orcid":false,"given":"Thomas K.","family":"Gaetjens","sequence":"additional","affiliation":[{"name":"Department of Chemical and Biomolecular Engineering, University of Tennessee, Knoxville, TN 37996"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4090-865X","authenticated-orcid":false,"given":"Jin","family":"Ou","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Indiana University, Bloomington, IN 47405-7102"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiong","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Indiana University, Bloomington, IN 47405-7102"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanqi","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Indiana University, Bloomington, IN 47405-7102"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.
