Mild respiratory SARS-CoV-2 infection can cause multi-lineage cellular dysregulation and myelin loss in the brain

Survivors of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection frequently experience lingering neurological symptoms, including impairment in attention, concentration, speed of information processing and memory. This long-COVID cognitive syndrome shares many features with the syndrome of cancer therapy-related cognitive impairment (CRCI). Neuroinflammation, particularly microglial reactivity and consequent dysregulation of hippocampal neurogenesis and oligodendrocyte lineage cells,

Association between vaccination status and reported incidence of post-acute long-COVID-19 symptoms in Israel: double dose Pfizer-BioNTech vaccination may have a protective effect.

An emerging and complex health problem that remains poorly characterized and understood is long coronavirus disease 2019 (Long COVID). The rapid outbreak of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the ongoing coronavirus disease 2019 (COVID-19) pandemic. Long COVID is a post-infection condition in which individuals do not recover completely for

NIH researchers develop first stem cell model of albinism to study related eye conditions

A human induced pluripotent stem cell colony from OCA1A patient. The image was acquired using a confocal microscope and is stained for pluripotency marker proteins. The red color depicts transcription factor OCT4, green is SSEA4 protein and blue represents the nucleus of the cells.NEI “Animals used to study albinism are less than ideal because they

Engineered Mesenchymal Stem Cells as a Biotherapy Platform for Targeted Photodynamic Immunotherapy of Breast Cancer

Interleukin-12 (IL12) is a pleiotropic cytokine with promising prospects for cancer immunotherapy. Though IL12 gene-based therapy could overcome the fatal hurdle of severe systemic toxicity, targeted delivery and tumor-located expression of IL12 gene remain the challenging issues yet to be solved. Photo-immunotherapy emerging as a novel and precise therapeutic strategy, which elaborately combines immune-activating agents

CAR-T-cell therapy has the potential to replace chemoimmunotherapy for second-line treatment of patients with refractory or relapsed large B-cell lymphoma (LBCL)

In the ZUMA-7 trial, at a median follow-up of 24.9 months, patients randomly assigned to receive CAR T-cell therapy with axicabtagene ciloleucel, or axi-cell (Yescarta) had a median event-free survival (EFS) of 8.3 months, compared with 2 months for patients randomly assigned to standard-of-care chemoimmunotherapy, reported Frederick L. Locke, MD, from the Moffitt Cancer Center
