Carla V. Rothlin is an Argentinian immunologist.She is professor of immunobiology at Dorys McConnell Duberg and professor of pharmacology at Yale University. Rothlin is also the co-leader of the Cancer Immunology Program at Yale Cancer Center as well as an Howard Hughes Medical Investigator faculty scholar.

Rothlin studies the mechanisms that regulate immune homeostasis and wound repair, with specific interests in cell death recognition, immune checkpoints, and cellular crosstalk in the context of injury and cell turnover. She has made fundamental discoveries about the roles of TAM receptors tyrosine kinase and their ligands in the regulation of inflammation. Rothlin is also a co-founder of the Global Immunotalks, a weekly series of virtual lectures on recent immunological research. The series began in 2020.[1]

Early life and education[edit]

Rothlin grew up in Buenos Aires, Argentina.[2] She was one of four girls, raised by her mother, a physician, and her father, a pharmacology researcher.[2] Rothlin was surrounded by laboratory science and clinical cases from a young age.[2]

After high school, Rothlin earned both undergraduate and graduate degrees in biochemistry from the University of Buenos Aires,[3] where was mentored by Ana Belén Elgoyhen and studied the biochemical properties of the nicotinic acetylcholine receptors in the inner ear.[4] Her work helped further scientific understanding of how efferent cholinergic fibers and inner ear hair cells communicate information from the brain back to the ear to mediate sensory tuning.[5][3]

Rothlin completed her graduate studies in 2002 and moved to San Diego, California for her postdoctoral work,[2] where she studied under Greg Lemke at the Salk Institute for Biological Studies. There, she became fascinated by TAM receptors, which Lemke had discovered in the 1990s, and their roles in immune homeostasis.[2] She then decided to study immunology in her postdoctoral research.[6]

During her postdoctoral studies, Rothlin was part of a team that discovered the role of TAM receptor tyrosine kinases, Tyro3, Axl, and MerTk, in the regulation of inflammation.[7] They found that Tyro3, Axl, and MerTk inhibit Toll-like receptor (TLR) and TLR-induced cytokine cascades in the innate immune response.[8] Specifically, cytokine-dependent TAM signalling is upregulated by type I interferon-STAT1 signalling leading to expression of cytokine and TLR suppressors, acting in an inflammatory negative feedback loops.[8]

Career and research[edit]

In 2009, Rothlin was recruited to Yale University, where she started a lab with her partner from Salk, Sourav Ghosh.[2] Rothlin became Assistant Professor of Immunobiology at Yale, and in 2016 joined the faculty of the Howard Hughes Medical Institute.[9] In 2018, Rothlin became director of Graduate Studies in Immunobiology at Yale.[10] In 2019, Rothlin was appointed Dorys McConnell Duberg Professor of Immunobiology.[10] She is also a Professor of Pharmacology as well as a member of the Yale Cancer Center and Co-Leader of the Cancer Immunology Program at Yale.[11]

Rothlin is a co-director of the Rothlin Ghosh Lab which focuses on exploring the mechanisms of immune regulation and homeostasis.[12] The Rothlin Gosh lab has made critical discoveries regarding TAM receptor tyrosine kinases, their ligands and the role their interactions serve as innate immune checkpoints in the regulation of the immune response.[7] They have specifically found that TAMs help to inhibit the innate immune response, that TAM ligand, protein S, can mediate the ability of T cells to limit dendritic cell activation, and their roles in control of type 2 immunity and phagocytosis of apoptotic cells.[13]

TAM receptors and immune homeostasis[edit]

Rothlin and her team discovered a mechanism by which the adaptive immune system helps to regulate chronic inflammation through controlling dendritic cells (DCs).[14] They found that T cells produce the TAM ligand, protein S, that acts on TAMs on DCs to limit the extent of their activation.[14] When they knocked out the Pros1 gene, encoding protein S, in T cells, they found an enhanced immune response and increased colitis.[14] They further proved that this mechanism of immune regulation in conserved in humans as well.[14] They further showed a mechanism by which viruses can take advantage of the TAM mediated immune regulation to avoid destruction.[15] They found that viruses coated with TAM ligands activate TAMs on dendritic cells which limits interferon signalling to help evade immune responses and enable replication.[15] Since they also showed that inhibiting TAM receptors can promote resistance to infection, this could be used as a therapeutic target for viral diseases.[15] In 2015, Rothlin's group characterized MERTK as a potent inhibitor of T cell activation through its interactions with Pros1 ligand in humans.[16]

Innate immune checkpoints in cancer[edit]

Rothlin's lab also explores the role TAMs play in cellular immunology and innate immune checkpoints in cancer.[6] Immune checkpoint blockade therapy has historically focused on the adaptive immune system, blocking the cellular breaking system on T cells (such as CTLA-4 and PD-1 inhibitors) to enhance immunogenicity of the tumor microenvironment and cytotoxicity tumor infiltrating cells.[17] Rothlin and her team are working upstream of T cell exhaustion markers, at the level of the innate immune system checkpoints which involve TAMs.[17] Since Rothlin found that TAMs help to mediate the repair and regrowth aspect of the innate immune response, blocking these molecules holds promise to keep the immune system in an inflammatory or defensive state to promote anti-tumor immunity.[17]

In collaboration with Miriam Merad’s group, Rothlin and her team found that Axl signalling induces the expression of PD-L1 on dendritic cells in the tumor environment, supporting the TAM receptor pathway as an upstream target for immunotherapy.[18] In 2017, Rothlin and her team showed further roles of Axl in tumor growth.[19] They found that Axl expression is upregulated in colorectal cancer and that limiting Axl expression prevented tumor cell migration and invasion.[19] They also found that Axl plays a role in B cell migration to tertiary lymphoid structures in cancer, and blocking Axl signalling limits B cell migration.[20]

Scientific outreach[edit]

Rothlin aims to improve the scientific community through her leadership roles and outreach projects.[1] Rothlin is a committee member for the Minority Affairs Committee for the American Association of Immunologists.[21] She is also a senior editor for Immunology and Inflammation at eLife.[22]

Rothlin is also the co-founder of the Global Immunotalks Lectures, which she started in 2020 along with her colleague, friend, and fellow immunologist Elina Zúñiga in an effort to make cutting-edge immunology accessible to a global audience without the need for travel.[6][23] Rothlin and Zúñiga invite a renowned immunologist to share their newest findings with a global audience over Zoom every Wednesday. The talks are recorded and posted to YouTube.[6] Rothlin and Zúñiga were also motivated to implement these talks as a way to increase the opportunities for access to the latest discoveries in an egalitarian manner.[1] They know from firsthand experience in Argentina that not everyone has access to the seminars and conferences that some laboratories do.[23] Global Immunotalks proved to be very successful at bringing people together virtually during the COVID-19 pandemic.[6] The event was so successful, the series is being continued into 2021.[1]
