We are interested in how GBS factors promote&nbsp;colonization and systemic infection.&nbsp;<\/p>\n<p>Specifically, we study the molecular mechanisms of the type VII secretion system (T7SS) in GBS and how its secreted proteins and toxins contribute to toxicity and inflammation during pathogenesis, as well as to mucosal colonization\/niche establishment by outcompeting other bacteria and modulating the immune response. Our research is highly interdisciplinary, spanning pathogenesis, biochemistry, structural biology, immunology, reproductive and gastrointestinal biology, and the microbiome. We employ microbiological, molecular, cellular, biochemical, and immunological methods, as well as cellular and animal models, to examine the impact of the T7SS on GBS interactions with microbes and the host.<\/p>\n","protected":false},"featured_media":1736192,"template":"","meta":{"_acf_changed":false,"inline_featured_image":false,"_links_to":"","_links_to_target":""},"otheraff":[],"phd-degree":[2570,2569],"primary":[2327],"research-discipline":[2487,2503,2507,2506,2490,2501],"research-opportunity":[2540,2549,2554,2557,2556,2543,2562],"training-grant":[],"class_list":["post-1731107","faculty-listing","type-faculty-listing","status-publish","has-post-thumbnail","hentry","phd-degree-phd-microbiology","phd-degree-phd-neuroscience","primary-microbiology-immunology-and-cancer-biology","research-discipline-biochemistry","research-discipline-immunology","research-discipline-infectious-diseases-biodefense","research-discipline-microbiology","research-discipline-molecular-biology","research-discipline-neuroimmunology","research-opportunity-ro-biochemistry","research-opportunity-ro-cellbiology","research-opportunity-ro-immunology","research-opportunity-ro-infectiousdiseases","research-opportunity-ro-microbiology","research-opportunity-ro-molecularbiology","research-opportunity-ro-neuroimmunology"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Spencer, Brady - Research Faculty Directory<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/med.virginia.edu\/faculty\/faculty-listing\/yws5hb\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Spencer, Brady - Research Faculty Directory\" \/>\n<meta property=\"og:description\" content=\"The Spencer lab studies host-pathogen interactions of Gram-positive bacteria, focusing on the major neonatal pathobiont Group B Streptococcus (GBS).
