Researchers identified a modified host protein as a potential risk factor for plasma cell dyscrasis. Individuals with high levels of SUMO-modified HSP90 are at increased risk of developing multiple myeloma and other related diseases.
Scientists from A*STAR's Bioprocessing Technology Institute uncover crucial role of DOK3 and SHP1 in plasma cell development and production. This discovery advances understanding of plasma cells and antibody response, potentially leading to improved treatment for patients with autoimmune diseases like lupus and multiple myeloma.
Associate Professor David Tarlinton will receive $1 million funding to study immune cells causing lupus. He aims to develop treatments that prevent or reverse the disease by inhibiting harmful antibody production.
Scientists at Emory Vaccine Center found that IL-21 is necessary for long-lasting antibody responses in mice against viral infections. The molecule stimulates germinal centers and supports T helper cells, leading to the generation of virus-specific long-lived plasma cells.
Researchers have identified a substance that prevents fluid accumulation and edema formation in the body, offering new hope for treating excessive fluid retention in patients with chronic heart failure. The discovery also reveals a new molecular mechanism controlling water homeostasis in the kidneys.
The discovery of the Mcl-1 gene's critical role in keeping antibody-producing cells alive could lead to better treatments for diseases like myeloma and chronic immune disorders. Without this gene, plasma cells die within two days.
Researchers have solved the atomic structure of closed plasminogen, a key player in the clot-busting process, revealing an 'Achilles' heel' that proteins bind to when it opens up. This discovery may lead to more effective clot-busting drugs for treating heart attacks and strokes.
Researchers discovered that intestinal B cells acquire functions allowing them to neutralize pathogens while in the gut, a complex balance between beneficial and harmful bacteria. This finding provides insight into the immune system's ability to fight infection without damaging beneficial bacteria and other essential cells.
Researchers at Humabs BioMed SA have discovered the first antibody to target all 16 hemagglutinin subtypes of influenza A, representing a promising treatment option for severe cases of flu.

The study found prompt rejection reversal, prolonged reductions in antibody levels, and improved organ function with suppression of recurrent rejection for at least five months.
A landmark analysis found that continuous treatment with Revlimid and dexamethasone improved overall survival and time to disease progression in multiple myeloma patients. Patients who continued therapy had significantly longer overall survival rates compared to those who discontinued treatment after 10 months or less.
The ECOG E4A03 study found that Revlimid plus low-dose dexamethasone improved three-year overall survival rates to 75% in the intent-to-treat population. Continuous therapy also achieved a 91% overall response rate with a high complete response and very good partial response rate.
Researchers have developed a novel gene delivery approach that targets smooth muscle cells in blood vessels, offering a new paradigm for cell-specific gene delivery. The approach uses an electric field to transiently permeabilize plasma membranes and a specific DNA sequence to control nuclear entry.

The malaria parasite affects antigen-presenting dendritic cells in mice, reducing their ability to activate helper T cells and produce cytokines. This impairment leads to the failure of B-cell activation and antibody production, compromising the immune system's response to infection.
Researchers identify a key pathway for targeting pDC function in HIV vaccine development. A decrease in blood pDC frequency is observed in chronic HIV infections, correlating with high viral load and reduced CD4 counts.
Babies who received reconstituted blood during heart surgery had shorter ICU stays (70.5 hours vs 97 hours) and spent less time on mechanical ventilation (36.3 hours vs 53 hours). The study, published in the New England Journal of Medicine, puts to rest a decades-long debate and could save patients and blood banks money.
