COVID-19/SARS-CoV-2 Related News
China Daily - "Despite a few mutations here and there, the virus is still SARS-CoV-2 and the disease is still COVID-19. Risk will be highest to the elderly, and to those in high-risk groups, such as people who are diabetic, overweight, (have) high blood pressure, or who have inborn errors of immunity," warned Dr. Jeremy Kamil, LSUHS associate professor.
CNN News 18 - India recorded on Monday 3,52,991 new Covid-19 cases and 2,812 deaths in the last 24 hours. The country saw 22.5 lakh new infections in the last one week, the highest ever the world has seen, pushing India’s health infrastructure to a brim.
BoomNews India - Number of COVID-19 cases in India is now at the highest per day in any country in the world. Dr. Jeremy Kamil, LSUHS virologist, discusses status of variants, vaccines, and transmissability.
BBC News - A coronavirus variant identified in India is being investigated by scientists across the world. However, it is not yet known how far it has spread or whether it is driving the deadly second wave of Covid in India itself. Dr Jeremy Kamil, a virologist at LSUHS, says, "I doubt whether the Indian variant is more infectious than the UK variant - and we must not panic."
Pitt News - “A variant is like a unique constellation of mutations while a mutation will be like one star in that constellation,” stated Jeremy Kamil, virologist at LSU Health Shreveport. “Alternatively, if a variant was a fingerprint, then a mutation will be one line that’s part of the fingerprint.”
NBC News - Jeremy Kamil, a virologist at LSU Health Shreveport, said that he wasn’t surprised this mutation was detected, as lab data suggests it would play a role in breakthrough cases.
WIRED - In countries without much sequencing, new versions of the COVID-19 virus can go unnoticed. Jeremy Kamil, microbiologist at LSUHS, says certain mutations help the virus thrive—to be better at replicating, perhaps, or better at finding its way into cells.
BBC News - Dr Jeremy Kamil, a virologist at LSU Health Shreveport, says if enough mutations happen in a viral family tree or a lineage, the virus can begin to function differently and the lineage can become a so-called 'variant of concern'.
KCBS Radio - We're taking a closer look at variants and how the current vaccines are performing against them. To answer your questions KCBS Radio's Stan Bunger spoke with Dr. Jeremy Kamil, an associate professor of microbiology and immunology at Louisiana State University Health Shreveport.
Nature.com - Ramped-up sequencing efforts are helping to identify mutations that might boost transmission or help a virus evade immune responses. For the scientists who have spent the past year poring over hundreds of thousands of coronavirus genomes, the United States has been an enigma.
NBC CT - LSU Health Shreveport Virologist Jeremy Kamil told NBC Connecticut Investigates that halting their spread will require other measures. Kamil was among a team of researchers that discovered seven new COVID-19 strains, known as "variants," aside from the variants first identified in the UK, South Africa, and Brazil.
NBC News - "There are certain variants that are more transmissible, and we have strong data on that, but the thing people should take away from the variant story is just: Don't let your guard down," said Dr. Jeremy Kamil, an associate professor of microbiology and immunology at Louisiana State University Health Shreveport.
The World - Lots of new coronavirus variants that have emerged in recent weeks. Beyond worries over how some of them may impact the pandemic, it’s also prompted concerns over what to name them, and the unintended harms of using shortcuts that link the variant to a specific country.
NPR - A virus that spreads a lot has many chances to mutate, and COVID-19 is doing both in this country. Researchers in the U.S. now say they've found at least seven new variants here.
The New York Times - “There’s clearly something going on with this mutation,” said Jeremy Kamil, a virologist at Louisiana State University Health Shreveport. "It’s unclear whether it makes the variants more contagious. But because the mutation appears in a gene that influences how the virus enters human cells, the scientists are highly suspicious."
Research
Major Research Interest
Human Cytomegalovirus (HCMV)
The Kamil laboratory is focused on human cytomegalovirus (HCMV), a beta-herpesvirus that is a leading cause of birth defects and of life-threatening infections in the immunocompromised. Dr. Kamil’s group employs molecular genetic and pharmacological approaches to tackle basic research questions concerning virus biology. NIH-sponsored projects in the Kamil laboratory concern HCMV cell tropism and the regulation of viral gene expression during myeloid cell differentiation. Our work on viral cell tropism stems from an interest in the viral endoplasmic reticulum (ER)-resident protein UL148, which influences the expression of a viral glycoprotein complex required for cell entry. Intriguingly, UL148 is also an immuneëvasin that impedes cell surface presentation of CD58. Recent findings from the lab indicate that UL148 activates an ancient ER stress response pathway called the unfolded protein response (UPR). The data suggest that UL148 stabilizes a viral glycoprotein called “gO” by interfering with ER-associated degradation (ERAD), a cellular pathway that removes misfolded proteins from the ER. Moreover, the observation that UL148 activates the UPR may prove relevant for understanding immune evasion mechanisms. Dr. Kamil’s areas of expertise include viral replication, viral protein kinases, protein-protein interactions, antiviral drug targets, ERAD, UPR, and proteostasis, cell stress responses, cell-cycle regulation, tumor suppressors, viral glycoproteins, and HCMV cell entry.
Human cytomegalovirus replication, regulation of viral cell tropism Human cytomegalovirus (CMV) is a widespread herpesvirus that infects a majority of the human population. Although CMV does not usually cause disease in healthy people, the virus often crosses the placenta to infect the developing fetus, which can result in serious birth defects. In addition, CMV causes life threatening infections in immunocompromised patients. A major goal of our laboratory is to help develop a better understanding of this complex viral pathogen. In 2015, we identified a virally-encoded glycoprotein, UL148, that impacts the virus’ ability to infect different types of human cells. UL148 modulates the expression of alternative viral glycoprotein complexes that play key roles in cell entry, which likely explains its effects on cell tropism. UL148 resides in the endoplasmic reticulum (ER), an organelle at which proteins destined for secretion are first synthesized, folded, and processed before they can be transported further along the secretory pathway. During infection, UL148 stabilizes a subset of newly synthesized viral glycoproteins before they mature beyond the ER to become incorporated into virions. In particular, UL148 regulates the abundance of multi-subunit glycoprotein complexes that are built upon a viral glycoprotein called glycoprotein H (gH), which is a central component of the cell entry machinery shared by all herpesviruses and an important target for the vaccines. Another set of projects in the lab are focused on trying to understand how the virus regulates its genes during infection. In certain cell types, CMV rapidly undergoes lytic replication, during which huge amounts of viral macromolecules are produced to drive the assembly and release of progeny virions, and the host cell is ultimately destroyed as a result. In other cell types, however, the virus persists in a largely silent state called “latency.” We are currently investigating how viral and cellular protein kinases work together to control whether or not the virus actively replicates.

Research: This lab has found that HCMV protein UL148 induces quality control structures, and formation of these structures are PERK dependent. My project is to identify the protein-protein interactions that are crucial for the formation of these quality control structures. I will use tandem affinity purification and other methods in attempts to elucidate the molecular mechanism of how 148 induces stress and to answer if its effects on Endoplasmic Reticulum Associated Degradation (ERAD) are specific.

Research: Human cytomegalovirus (HCMV) relies on viral glycoprotein complexes that orchestrate membrane fusion events required to deliver the viral genome to host cells. Unsurprisingly, viral entry triggers innate antiviral defenses, such as type I interferons. However, HCMV circumvents antiviral defenses, progresses throughout its lifecycle, and establishes infection. My project tests the hypothesis that certain HCMV glycoproteins enable viral entry in the face of antiviral defense signals.
