Laboratory of Host Immunity and Microbiome (LHIM)

Niki M. Moutsopoulos, D.D.S., Ph.D., Chief

The vision of the Laboratory of Host Immunity and Microbiome (LHIM) is to comprehensively examine the factors controlling immunity and inflammation, whether they are host intrinsic (e.g., tissue-specific or the consequence of tissue-tissue communication) or extrinsic (e.g., involving the microbiota, nutrition, or infection). One major goal of the laboratory is to assess the consequences of environmental stress, such as microbiota colonization, nutrition, and pollution, on host immunity and predisposition to chronic inflammatory disorders at barrier surfaces, such as the gastrointestinal and respiratory mucosa, in the context of early life and into adulthood. The laboratory also seeks to explore novel microbiota-mediated and immunotherapeutic approaches to target human (mucosal) disease. The laboratory is built upon strong clinical-basic research foundations and partnerships with the NIH Clinical Center and the NIAID Microbiome Program.

LHIM has been specifically organized to maximize the capacity of its investigators to conduct cutting-edge research. It is home to the NIAID Microbiome Program,  which supports microbiome-related research through gnotobiotic, microbiology, and genomic core services. A major emphasis of LHIM is to promote collaborations between the laboratories within NIAID, as well as with the larger NIH (including the larger NIH immunology community) and extramural scientific communities. LHIM also has a strong emphasis on mentorship and fostering the next generation of scientific leaders.

Major Areas of Research

LHIM utilizes transdisciplinary approaches in the exploration of host-microbe, tissue-tissue, and host-environment interactions. Areas of research focus include:

  • Immunology (e.g., human immunology, immunometabolism, nutritional immunology)
  • Microbiology (e.g., microbial ecology, antimicrobial resistance)
  • Chemistry (e.g., microbiota-derived natural products)
  • Neuroscience (e.g., gut/brain axis)
  • Genomics

In these latter cases, the lab has a particular interest in how such studies would enhance our understanding of host immunity.

Networks

  • The NIAID Microbiome Program is a collaborative effort to explore the metaorganism. The Program supports microbiome-related research through gnotobiotic, microbiology, and genomic core services.
  • The Center for Human Immunology (CHI) is a trans-NIH initiative to achieve an integrated understanding of human immunity and the microbiome in health and disease.

Sasisekhar Bennuru, Ph.D.

Associate Scientist, Helminth Immunology Section

Major Areas of Research

  • Molecular characterization of helminth parasites with a focus on filarial infections
  • Development of diagnostics and biomarker discovery for helminth infections
  • Host-parasite interactions towards defining pathogenesis of filarial infection

Biography

Dr. Bennuru received his Ph.D in 2005 from the Center for Biotechnology, Anna University in Chennai, India. He joined NIH in 2005 as a post-doctoral research fellow with Dr. Thomas Nutman in the Laboratory of Parasitic Diseases, primarily working on cellular and molecular aspects of human filarial infections and has been a staff scientist since 2013.

Program Description

Dr. Bennuru’s research focus within the Helminth Immunology Section is a multi-omic approach to understand the biology of parasitic helminths (especially human filarial infections, e.g., lymphatic filariasis, onchocerciasis, and loiasis) and the host-parasite interaction toward defining pathogenesis; to identify parasite-encoded therapeutic, diagnostic, and vaccine-related targets; and to develop biomarkers of species-specific filarial infection.
