Innovative Cancer Treatment Found To Be Promising For The Control Of Fungal Infections
Publicado em 05 março 2021
An innovative cell-based treatment for cancer has been found promising for the control of infections caused by fungi. A study published in the journal Cytotherapy reports that the use of chimeric antigen receptor (CAR) T-cells programmed to recognize Cryptococcus spp. fungi was effective in combating infection in vitro and in mice.
C. gattii and C. neoformans are present in soil with dead organic matter and places contaminated by the droppings of pigeons and other birds. They cause systemic [...]

Studies use mathematics to analyze the semantics of dream reports during the pandemic
Publicado em 04 fevereiro 2021The COVID-19 pandemic has affected people’s behavior everywhere. Fear, apprehensiveness, sadness, anxiety, and other troublesome feelings have become part of the daily lives of many families since the first cases of the disease were officially recorded early last year. These turbulent feelings are often expressed in dreams reflecting a heavier burden of mental suffering, fear of contamination, stress caused by social distancing, and lack of physical contact with others. In addition, [...]ver notícia -
Discovery of protein’s ‘Achilles heel’ paves way for novel class of anti-HIV drugs
Publicado em 17 novembro 2020The discovery of a potential “Achilles heel” in Nef, the protein that is crucial to HIV virulence and its capacity to trigger AIDS, paves the way for the development of a new class of drugs against the virus. Researchers have succeeded in demonstrating a structure that binds this protein to another called AP-2 and regulates endocytosis, the process by which cells take in substances such as nutrients or pathogens by engulfing them in a vesicle. As a result, it is increasingly clear [...]ver notícia -
Study identifies key enzyme for development of autoimmune diseases
Publicado em 20 outubro 2020Scientists affiliated with the Center for Research on Inflammatory Diseases (CRID), hosted by the University of São Paulo (USP) in Brazil, have discovered that an enzyme involved in key metabolic processes also plays a role in immune cell differentiation and hence in the development of autoimmune diseases. The finding could contribute to the future development of new treatments and more cost-effective and resolutive medications for this kind of disease. The study is reported in the [...]ver notícia -
A study investigating genetic mechanisms underlying resistance to leishmaniasis
Publicado em 25 março 2020In an article published in Scientific Reports, researchers affiliated with the University of São Paulo (USP) in Brazil describe experiments performed with mice that show how genetic factors can determine whether an individual is susceptible or resistant to leishmaniasis. According to the authors, the results will contribute to a better understanding of leishmaniasis in humans and help to clarify why only some of those individuals infected develop the disease. Leishmaniasis is caused by [...]ver notícia -
Zika inhibits the proliferation of prostate cancer cells
Publicado em 21 janeiro 2020After revealing in a groundbreaking study that Zika virus can be used to combat brain tumors, researchers at the University of Campinas (UNICAMP) in São Paulo State, Brazil, have shown that the pathogen may also be a weapon against prostate cancer. The study was led by Rodrigo Ramos Catharino, a professor in UNICAMP’s School of Pharmaceutical Sciences. In experiments with a human prostate adenocarcinoma cell line (PC-3), the scientists found that Zika inhibits tumor cell [...]ver notícia -
Mechanism that triggers the inflammatory process by Mayaro virus is discovered
Publicado em 02 dezembro 2019The mechanism by which defense cells respond to infection by the Mayaro virus has been described by a team affiliated with the Center for Research on Inflammatory Diseases (CRID) in an article published in the journal PLOS Pathogens. According to the authors, by establishing an experimental model of Mayaro fever in adult mice and identifying the processes involved in the immune response, the study provides a basis for the development of drugs against this disease. CRID is one of the [...]ver notícia -
Biophotonic therapy eliminates bacteria and viruses from organs before transplantation
Publicado em 12 abril 2019A new technique for the decontamination of organs before transplantation using ultraviolet and red light irradiation has been developed by Brazilian and Canadian researchers and is described in an article published in the journal Nature Communications. The research is supported by São Paulo Research Foundation — FAPESP and has been partially conducted at the Optics and Photonics Research Center (CEPOF), hosted by the University of São Paulo (USP) at São Carlos in São Paulo State [...]ver notícia
