Early life and education

Moscona was born in Chicago, Illinois, where her parents, Aron Moscona [6] [7] and Malka Moscona, [8] were Israeli-American developmental biologists at the University of Chicago. [9] [10] Moscona received her BA in Molecular Biology & Biochemistry from Harvard University in 1978, and MD from Columbia University College of Physicians and Surgeons in 1982. [11]

Career

Moscona completed her clinical and research training at Mount Sinai Health System in New York City. She was promoted to tenured professor in 2001 and served as chief of pediatric infectious diseases and vice chair for research until 2005. In 2005, she became professor of Pediatrics and of Microbiology and Immunology, vice chair for research of Pediatrics, and Chief of Pediatric Infectious Diseases at the Weill Cornell Medical Center, [12] before moving to Columbia in 2015 as a tri-departmental professor and center director. Moscona's research focuses on understanding how viruses enter human cells and how to use this knowledge to design better tools to prevent viral infection. [13] Her research program focuses on paramyxoviruses, a family of negative-sense RNA viruses that cause severe illness in humans, [14] [15] [16] and her group has developed new techniques to block viral infection through fusion inhibition, [17] [18] most recently developing fusion inhibitory peptides for SARS-CoV-2. [19] [20] She is frequently consulted as a  medical expert during viral outbreaks, including epidemic and pandemic influenza. [21] [22] [23] Her research has been featured in outlets including Nature, Science, the New England Journal of Medicine, the New York Times, CNN, NBC, ABC and The Hill. [24] [25] [26]

COVID-19

On November 5, 2020, the New York Times reported that Moscona's research group had collaboratively developed “A nasal spray that blocks the absorption of the SARS-CoV-2 virus...” and that it had “...completely protected ferrets it was tested on, according to a small study...” [27] According to the article, the therapeutics are patent pending and awaiting market production.

Coronaviruses are a group of related RNA viruses that cause diseases in mammals and birds. In humans and birds, they cause respiratory tract infections that can range from mild to lethal. Mild illnesses in humans include some cases of the common cold, while more lethal varieties can cause SARS, MERS and COVID-19. In cows and pigs they cause diarrhea, while in mice they cause hepatitis and encephalomyelitis.

<span class="mw-page-title-main">SARS-related coronavirus</span> Species of coronavirus causing SARS and COVID-19

Betacoronavirus pandemicum is a species of virus consisting of many known strains. Two strains of the virus have caused outbreaks of severe respiratory diseases in humans: severe acute respiratory syndrome coronavirus 1, the cause of the 2002–2004 outbreak of severe acute respiratory syndrome (SARS), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the cause of the pandemic of COVID-19. There are hundreds of other strains of SARSr-CoV, which are only known to infect non-human mammal species: bats are a major reservoir of many strains of SARSr-CoV; several strains have been identified in Himalayan palm civets, which were likely ancestors of SARS-CoV-1.

<span class="mw-page-title-main">Epstein–Barr virus</span> Virus of the herpes family

The Epstein–Barr virus (EBV), formally called Human gammaherpesvirus 4, is one of the nine known human herpesvirus types in the herpes family, and is one of the most common viruses in humans. EBV is a double-stranded DNA virus. Epstein–Barr virus (EBV) is the first identified oncogenic virus, which establishes permanent infection in humans. EBV causes infectious mononucleosis and is also tightly linked to many malignant diseases. Various vaccine formulations underwent testing in different animals or in humans. However, none of them were able to prevent EBV infection and no vaccine has been approved to date.

<span class="mw-page-title-main">Defective interfering particle</span>

Defective interfering particles (DIPs), also known as defective interfering viruses, are spontaneously generated virus mutants in which a critical portion of the particle's genome has been lost due to defective replication or non-homologous recombination. The mechanism of their formation is presumed to be as a result of template-switching during replication of the viral genome, although non-replicative mechanisms involving direct ligation of genomic RNA fragments have also been proposed. DIPs are derived from and associated with their parent virus, and particles are classed as DIPs if they are rendered non-infectious due to at least one essential gene of the virus being lost or severely damaged as a result of the defection. A DIP can usually still penetrate host cells, but requires another fully functional virus particle to co-infect a cell with it, in order to provide the lost factors.

<i>Human metapneumovirus</i> Species of virus

Human metapneumovirus is a negative-sense single-stranded RNA virus of the family Pneumoviridae and is closely related to the Avian metapneumovirus (AMPV) subgroup C. It was isolated for the first time in 2001 in the Netherlands by using the RAP-PCR technique for identification of unknown viruses growing in cultured cells. As of 2016, it was the second most common cause of acute respiratory tract illness in otherwise-healthy children under the age of 5 in a large US outpatient clinic.

Coinfection is the simultaneous infection of a host by multiple pathogen species. In virology, coinfection includes simultaneous infection of a single cell by two or more virus particles. An example is the coinfection of liver cells with hepatitis B virus and hepatitis D virus, which can arise incrementally by initial infection followed by superinfection.

<span class="mw-page-title-main">Human parainfluenza viruses</span> Viruses that cause human parainfluenza

Human parainfluenza viruses (HPIVs) are the viruses that cause human parainfluenza. HPIVs are a paraphyletic group of four distinct single-stranded RNA viruses belonging to the Paramyxoviridae family. These viruses are closely associated with both human and veterinary disease. Virions are approximately 150–250 nm in size and contain negative sense RNA with a genome encompassing about 15,000 nucleotides.

<i>Human coronavirus NL63</i> Species of virus

Human coronavirus NL63 (HCoV-NL63) is a species of coronavirus, specifically a Setracovirus from among the Alphacoronavirus genus. It was identified in late 2004 in patients in the Netherlands by Lia van der Hoek and Krzysztof Pyrc using a novel virus discovery method VIDISCA. Later on the discovery was confirmed by the researchers from Rotterdam. The virus is an enveloped, positive-sense, single-stranded RNA virus which enters its host cell by binding to ACE2. Infection with the virus has been confirmed worldwide, and has an association with many common symptoms and diseases. Associated diseases include mild to moderate upper respiratory tract infections, severe lower respiratory tract infection, croup and bronchiolitis.

<i>Herpesviridae</i> Family of DNA viruses

Herpesviridae is a large family of DNA viruses that cause infections and certain diseases in animals, including humans. The members of this family are also known as herpesviruses. The family name is derived from the Greek word ἕρπειν, referring to spreading cutaneous lesions, usually involving blisters, seen in flares of herpes simplex 1, herpes simplex 2 and herpes zoster (shingles). In 1971, the International Committee on the Taxonomy of Viruses (ICTV) established Herpesvirus as a genus with 23 viruses among four groups. As of 2020, 115 species are recognized, all but one of which are in one of the three subfamilies. Herpesviruses can cause both latent and lytic infections.

Simian foamy virus (SFV) is a species of the genus Spumavirus that belongs to the family of Retroviridae. It has been identified in a wide variety of primates, including prosimians, New World and Old World monkeys, as well as apes, and each species has been shown to harbor a unique (species-specific) strain of SFV, including African green monkeys, baboons, macaques, and chimpanzees. As it is related to the more well-known retrovirus human immunodeficiency virus (HIV), its discovery in primates has led to some speculation that HIV may have been spread to the human species in Africa through contact with blood from apes, monkeys, and other primates, most likely through bushmeat-hunting practices.

<i>Murine respirovirus</i> Sendai virus, virus of rodents

Murine respirovirus, formerly Sendai virus (SeV) and previously also known as murine parainfluenza virus type 1 or hemagglutinating virus of Japan (HVJ), is an enveloped, 150-200 nm–diameter, negative sense, single-stranded RNA virus of the family Paramyxoviridae. It typically infects rodents and it is not pathogenic for humans or domestic animals.

<span class="mw-page-title-main">Viral entry</span> Earliest stage of infection in the viral life cycle

Viral entry is the earliest stage of infection in the viral life cycle, as the virus comes into contact with the host cell and introduces viral material into the cell. The major steps involved in viral entry are shown below. Despite the variation among viruses, there are several shared generalities concerning viral entry.

<span class="mw-page-title-main">Antibody-dependent enhancement</span> Antibodies rarely making an infection worse instead of better

Antibody-dependent enhancement (ADE), sometimes less precisely called immune enhancement or disease enhancement, is a phenomenon in which binding of a virus to suboptimal antibodies enhances its entry into host cells, followed by its replication. The suboptimal antibodies can result from natural infection or from vaccination. ADE may cause enhanced respiratory disease, but is not limited to respiratory disease. It has been observed in HIV, RSV virus and Dengue virus and is monitored for in vaccine development.

<span class="mw-page-title-main">Hemagglutinin</span> Substance that causes red blood cells to agglutinate

In molecular biology, hemagglutinins are receptor-binding membrane fusion glycoproteins produced by viruses in the Paramyxoviridae and Orthomyxoviridae families. Hemagglutinins are responsible for binding to receptors on red blood cells to initiate viral attachment and infection. The agglutination of red cells occurs when antibodies on one cell bind to those on others, causing amorphous aggregates of clumped cells.

As of 2024, a vaccine against Epstein–Barr virus was not yet available. The virus establishes latent infection and causes infectious mononucleosis. There is also increasingly more evidence that EBV may be a trigger of multiple sclerosis. It is a dual-tropic virus, meaning that it infects two different host cell types — in this case, both B cells and epithelial cells. One challenge is that the Epstein–Barr virus expresses very different proteins during its lytic and its latent phases. Antiviral agents act by inhibiting viral DNA replication, but as of 2016, there was little evidence that they are effective against Epstein–Barr virus, they are expensive, they risk causing resistance to antiviral agents, and can cause unpleasant side effects.

<i>Human coronavirus HKU1</i> Species of virus

Human coronavirus HKU1 (HCoV-HKU1) is a species of coronavirus in humans and animals. It causes an upper respiratory disease with symptoms of the common cold, but can advance to pneumonia and bronchiolitis. It was first discovered in January 2004 from one man in Hong Kong. Subsequent research revealed it has global distribution and earlier genesis.

<i>Human coronavirus 229E</i> Species of virus

Human coronavirus 229E (HCoV-229E) is a species of coronavirus which infects humans and bats. It is an enveloped, positive-sense, single-stranded RNA virus which enters its host cell by binding to the APN receptor. Along with Human coronavirus OC43, it is one of the viruses responsible for the common cold. HCoV-229E is a member of the genus Alphacoronavirus and subgenus Duvinacovirus.

<i>Pneumoviridae</i> Family of viruses

Pneumoviridae is a family of negative-strand RNA viruses in the order Mononegavirales. Humans, cattle, and rodents serve as natural hosts. Respiratory tract infections are associated with member viruses such as human respiratory syncytial virus. There are five species in the family which are divided between the genera Metapneumovirus and Orthopneumovirus. The family used to be considered as a sub-family of Paramyxoviridae, but has been reclassified as of 2016.
