Immunohistochemistry (IHC) is an imaging technique to visualize antigens in cells. Labeled antibodies bind to target antigens in the cell to image the distribution and localization of specific proteins of interest

Researchers develop comprehensive framework to classify small-cell lung cancer

Researchers from The University of Texas MD Anderson Cancer Center have developed the first comprehensive framework to classify small-cell lung cancer (SCLC) into four unique subtypes, based on gene expression, and have identified potential therapeutic targets for each type in a study published today in Cancer Cell.

SARS-CoV-2 infected alveolar type-II lung cells show senescence

Using monoclonal antibodies against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein and senescent markers, researchers provide evidence that virus-infected lung cells acquire characteristics of cellular senescence, which also leads to expression of proinflammatory cytokines.

68Ga-pentixafor PET imaging is an effective diagnostic tool for CNS B-cell lymphoma

Positron emission tomography (PET) imaging with 68Ga-pentixafor is an effective diagnostic tool for central nervous system (CNS) B-cell lymphoma, according to a proof-of-concept study published in the December issue of The Journal of Nuclear Medicine.

Study exposes human olfactory and brain cells as genuine viral targets of SARS-CoV-2

In a study published in the iScience journal, a research group from Switzerland shows that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) receptors and entry genes are expressed in the human olfactory neuroepithelial cells and brain by observing key molecular players implicated in the infectious process

Goblet cells are prime target for SARS-CoV-2, study finds

A recent study reports that in the airway of patients with chronic obstructive pulmonary disease (COPD), a type of airway epithelial cell – called a goblet cell – presents a prime target for the virus and plays a vital role in promoting viral replication in this tissue.

SARS-CoV-2 viral antigens found in non-pulmonary tissues in recovering patients

A team of researchers in Singapore, led by Dr. Joe Yeong, and Prof. Tony Kiat Hon Lim, have reported the presence of residual SARS-CoV-2 ribonucleic acid (RNA) – the virus' genetic material – in stool samples and gastrointestinal tissues from patients recovering from the coronavirus disease 2019 (COVID-19).

Chikungunya can infect central nervous system and impair cognitive, motor functions

A study conducted by an international team of researchers with FAPESP's support shows that infection by chikungunya virus can produce even more severe manifestations than the typical symptoms of the disease, such as acute fever, headache, rash, and intense joint and muscle pain.

Multimodal mapping of immune landscape in pancreatic cancer could guide personalized therapies

Pancreatic cancer has remained resistant to immunotherapies that are revolutionizing the treatment of many types of cancer.

New diagnostic method may allow for real-time detection of cancer growth patterns

Using a 2 ml blood sample from 100 gastric cancer patients, researchers succeeded in identifying cancer cells circulating in the bloodstream and trace them back to their origin tumor by detecting an overexpression of fibroblast growth factor receptor (FGFR2) in both the cancer cells and the tumor.

3D imaging of SARS-CoV-2 infection in ferrets using light sheet microscopy

Researchers from the Friedrich-Loeffler-Institut, Federal Research Institute for Animal Health demonstrate the ability to detect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in 3D tissue samples in ferrets. This will allow the detection of infection patterns in tissues and their interrelations.

SARS-CoV-2 infection of carotid arteries may explain vascular involvement in COVID-19

A new study published on the preprint server bioRxiv in October 2020 shows that the virus causing COVID-19, namely, SARS-CoV-2, produces replicative infection in the carotid arteries and affects the vascular responses. This could have a profound bearing on the understanding of the disease and its clinical treatment.

New clinical report on brain changes in deceased COVID-19 patients

German researchers published a report on a series of cases on post mortem findings of COVID-19 patients who succumbed to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection along with neurological complications. Their study titled “Neuropathology of patients with COVID-19 in Germany: a post-mortem case series” is published in the latest issue of The Lancet Neurology.

Lung tissue in fatal COVID-19 shows broad cell tropism and extensive damage

In a recent preprint paper published on the medRxiv server, researchers demonstrated their investigation of fatal COVID-19 patients to assess infection in various cell types and the extent of damage it caused to the lung tissues.
