An influenza mRNA vaccine protects ferrets from lethal infection with highly pathogenic avian influenza A(H5N1) virus.

The global spread of the highly pathogenic avian influenza (HPAI) A(H5N1) virus poses a serious pandemic threat, necessitating the swift development of effective vaccines. The success of messenger RNA (mRNA) vaccine technology in the COVID-19 pandemic, marked by its rapid development and scalability, demonstrates its potential for addressing other infectious threats, such as HPAI A(H5N1). We therefore evaluated mRNA vaccine candidates targeting panzootic influenza A(H5) clade 2.

Mechanistic and Therapeutic Implications of Protein and Lipid Sialylation in Human Diseases.

Glycan structures of glycoproteins and glycolipids on the surface glycocalyx and luminal sugar layers of intracellular membrane compartments in human cells constitute a key interface between intracellular biological processes and external environments. Sialic acids, a class of alpha-keto acid sugars with a nine-carbon backbone, are frequently found as the terminal residues of these glycoconjugates, forming the critical components of these sugar layers. Changes in the status and content of cellular sialic acids are closely linked to many human diseases such as cancer, cardiovascular, neurological, inflammatory, infectious, and lysosomal storage diseases.

Production of recombinant adeno-associated virus 5 using a novel self-attenuating adenovirus production platform.

Recombinant adeno-associated virus (rAAV) has become a prominent vector for clinical use. Despite an increase in successful clinical outcomes, the amount of high-quality rAAVs required for clinical trials and eventual commercial demand is difficult to produce, especially for genetic diseases that are prevalent or require high doses. Many groups are focused on establishing production processes that can produce sufficient rAAV while maintaining potency and quality.

Spontaneous Renal Artery Dissection in Active Duty Male.

Spontaneous renal artery dissection is a rare condition with nonspecific symptoms that can be challenging to diagnose. We present the case of a 25-year-old male presenting with left flank pain, mild leukocytosis, and a benign urinalysis found to have renal artery dissection on computed tomography angiogram. The patient's condition improved following conservative management with anticoagulants.
