Portuguese Research Center Discovers Mechanism That May Explain Greater or Less Severity of Infection – The Observer



Portuguese Research Center Discovers Mechanism That May Explain Greater or Less Severity of Infection - The Observer

Researchers at the Institute for Health Research and Innovation (i3S) have discovered a mechanism related to T cell alteration that may explain why SARS-CoV-2 infection causes mild to severe illness in humans.

In a statement from the Institute of the University of Porto on Wednesday, it was published that researchers had discovered a mechanism that “may explain why SARS-CoV-2 infection causes mild or even asymptomatic illness some people have severe and complex illnesses in others. “

The results of the study, funded by the Research 4 Covid Initiative of the Science and Technology Foundation (FCT), were published in the Journal of Immunology, and the article was noted as a “top reader” for the September issue.

A study by researcher Salome Pinho showed that circulating T cells “exchange their glycans.” [moléculas de açúcar] especially after infection with SARS-CoV-2 “and that this change “More pronounced” in asymptomatic people than in symptomatic people


“Thus, an immunological response is determined based on glycosylated forms of T-lymphocytes, which provides protection against the virus,” the institute assured.

The alteration of the glycosylation profile in the immune response after infection with SARS-CoV-2 “appears to be caused by an inflammatory factor present in the plasma of the individuals.”

According to researcher Salome Pinho, this specific T-cell glycosignature, more pronounced in asymptomatic patients, “can be detected at diagnosis” and represents “A new biomarker of severity and prognosis of Covid-19, as well as a new therapeutic target”

In parallel, the research team demonstrated that asymptomatic patients have mononuclear blood cells exhibit “increased expression of a specific protein”capable of efficiently recognizing the virus and the level of expression of which in monocytes [células inflamatórias que pertencem à primeira linha de defesa] correlated with “better patient prognosis”.

Also mentioned in the paper, Ines Alves and Manuel Vicente, the first authors of the study, say it is important to emphasize that this mechanism associated with SARS-CoV-2 infection “may be related to another type of respiratory viral infections that are opening up. new opportunities for the study of other infectious diseases ”.

The role of T lymphocytes in resolving or exacerbating Covid-19, as well as the ability to provide long-term protection against re-infection with SARS-CoV-2, “remains to be fully disclosed,” notes i3S.

The investigation looked to the cooperation of the University Hospital Center of Porto and the Hospital Center Vila Nova de Gaia / Espinho.

According to the latest report from Agence France-Presse, the Covid-19 pandemic has caused at least 4,234,618 deaths worldwide out of more than 198.8 million infections with the new coronavirus.

In Portugal, 17,397 people have died and 974,203 cases have been reported since the pandemic began in March 2020, according to the General Directorate of Health.

The respiratory illness is caused by the SARS-CoV-2 coronavirus, discovered in late 2019 in Wuhan, a city in central China, and currently variants identified in countries such as the UK, India, South Africa, Brazil and Peru.

When asked about the reasons why Margarida Tavares’ name still does not appear in the Diário da República, the official said that “it was necessary to wait for the inauguration of the secretaries of state” and then “to organize the whole process of delegation of authority.” .

Mutirão Opens To Negotiation Of Individuals' Overdue Debts - Português (Brazil)

September is a very important and visible month for deaf people, with three dates that raise awareness and celebrate achievements that are part of the entire community’s trajectory and struggle. These are: – International Sign Language Day, September 23; – Day of the Deaf, 26 September; and Libra National Interpreter and Translator Day on September 30th. With a focus on the deaf community, the Department of Education is promoting several initiatives in this area.

The first is aimed at changing the scenario of educational and language policy based only on the inclusive perspective of including a deaf student in the school environment without guaranteeing procedures that enhance accessibility in his education. The National Guidelines for Bilingual Education for the Deaf integrate all stages of basic education and are based on the promotion of bilingual curricula and pedagogical practices for the deaf: Brazilian Sign Language (Libras) and written Portuguese.

Through the Department of Special Education, the MEC coordinates with interested municipalities the construction, renovation or expansion of bilingual schools for the deaf. To date, 11 locations in Brazil have shown interest in the project. To complement this phase, the Libras National Textbook Program (PNLD) provides accessible formats to deaf students and public school teachers of basic education in the country.

In the academic world, in partnership with universities, advanced training courses are offered for teachers, managers and professionals who want to work with bilingual education for the deaf. Thanks to the projects of various institutions, there are currently 3,520 vacancies for teaching the deaf.

On the Internet, Canal Libras is a space for communication and content distribution with a focus on the national educational network, from early childhood education to higher education.


Another important date: The National Institute for Education for the Deaf (Ines) turns 165 on the same Libra and the Deaf Day, September 26th. Within the structure of the Ministry of Education, the Institute stands out as a national reference in the field of deafness, necessary to support the formulation of public policies, and then for their implementation in the field. The Institute works to promote education for deaf children, youth and adults.
