This study prepared a novel monoclonal antibody (MAb) against mink enteritis parvovirus (MEV) and identified its antigen epitope. The antibody subclass is identified as IgG1, the titers of the MAb is up to 1:1 × 10 and keeps stably after low-temperature storage for 9 months or 11 passages of the MAb cells. The MAb can specifically recognize MEV in the cells in IFA, but not Aleutian disease virus (ADV) or canine distemper virus (CDV). Its antigen epitope was identified as a polypeptide containing 5 key amino acids (YAFGR) and the homology in 20 MEV strains, 4 canine parvovirus strains, and 4 feline panleukopenia virus strains was 100%. This study supplies a biological material for developing new methods to detect MEV.

Highly pathogenic avian influenza (HPAI) H5N1 virus poses a continuing global public health threat due to its outbreaks in poultry farms and zoonotic transmission from birds to humans. In the quest of effective therapeutics against H5N1 infection, antibodies with broad neutralizing activity have attracted significant attention. In this study, we employed a phage display technique to select and identify VHH antibodies with specific neutralizing activity against H5N1 hemagglutinin (HA) from an immune llama-derived antibody library.

Antibody-based therapies have revolutionized cancer treatment but have several limitations. These include: down-regulation of the target antigen; mutation of the target epitope; or in the case of antibody drug conjugates (ADCs), resistance to the chemotherapy warhead. Since TROP2-targeted therapy with ADCs yields responses in TROP2+ solid tumors but lacks the durability observed with other immunotherapy-based approaches, we developed novel TROP2-targeting chimeric antigen receptor (CAR) T cells as an alternative.

The 2022/2023 season witnessed a rapid resurgence of H1N1pdm09 in Anhui Province, China, surpassing previous years, prompting an examination of hemagglutinin (HA) gene mutations and cross-immunity in this study. Anhui Province's surveillance data established the detection threshold for H1N1pdm09 using the Moving Epidemic Method. Joinpoint regression compared weekly percent change (WPC) rates.

Longitudinal extensive transverse myelitis (LETM) is a rare adverse event after vaccination. We present a case of severe myelitis in a 76-year-old man with positive anti-recoverin antibodies that occurred one week after RSVPreF3 vaccination against respiratory syncytial virus (RSV). The patient presented with severe spastic paraparesis, urinary retention, postural tremor of the upper extremities, hypesthesia, severely impaired proprioception and vibration sense in the lower extremities, and tonic spasms of the lower extremities.
