B-cell therapy in lupus nephritis: an overview
1Division of Nephrology, Department of Internal Medicine and Davis Heart and Lung Research Institute, The Ohio State University Medical Center, Columbus, OH, USA.
Summary
B-cell therapies show promise for treating lupus nephritis (LN), a kidney complication of systemic lupus erythematosus (SLE). Reviewing past trials reveals challenges, suggesting new B-cell-focused strategies are needed for effective LN management.
Area of Science:
- Immunology
- Nephrology
- Rheumatology
Background:
- Systemic lupus erythematosus (SLE) is an autoimmune disease impacting multiple organs, frequently involving the kidneys.
- Autoantibody production by B-cells, plasmablasts, and plasma cells is central to lupus nephritis (LN) pathogenesis.
- B-cells represent a key therapeutic target in managing LN.
Purpose of the Study:
- To review the clinical experience with B-cell therapies in lupus nephritis.
- To identify limitations and challenges encountered in randomized clinical trials of B-cell therapies for LN.
- To propose B-cell-centric management strategies for LN based on existing data.
Main Methods:
- Review of randomized clinical trials, cohort studies, and observational data on B-cell therapies in LN.
- Analysis of factors contributing to the success or failure of B-cell-targeted treatments.
- Synthesis of findings to inform future therapeutic approaches.
Main Results:
- Randomized trials of B-cell therapies in LN have yielded disappointing results.
- Uncontrolled cohort and observational studies suggest potential benefits of B-cell antagonists.
- Discrepancies between trial types highlight complexities in evaluating B-cell therapies for LN.
Conclusions:
- Current B-cell therapies have not fully met expectations in randomized LN trials.
- Further investigation into B-cell-centric approaches is warranted for effective LN treatment.
- Understanding the nuances of B-cell biology in SLE is crucial for optimizing LN management.

01:26Drug Administration and Therapy Phases: Overview
1.4K
Drugs, the chemical agents used in diagnosing, treating, or preventing diseases, undergo a four-phase process of development: pharmaceutic, pharmacokinetics, pharmacodynamics, and therapeutic.
The pharmaceutical phase focuses on leveraging the physicochemical properties of the drug to design and manufacture an effective product. Variants include orally administered tablets or capsules, topical creams or ointments, and parenteral-delivery solutions or emulsions.

27.6K
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

01:14Overview of Cell-Cell Junctions
29.9K
The complex three-dimensional arrangement of cells in any multicellular organism is defined and maintained by interactions of cells with each other and the extracellular matrix. Cell-cell junctions are specialized structures where the multi-protein complexes on one cell interact with the multi-protein complexes on another cell. These cell junctions are classified into three main types based on their function — occluding, anchoring, and gap junctions.

01:23Overview of Cell Signaling
24.9K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate with the environment.
Cells respond to many types of information, often through receptor proteins positioned on the membrane. For example, skin cells respond to and transmit touch...

01:30Overview of Cell Death
10.1K
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

01:20Overview Of Cell Separation And Isolation
7.6K
Cell separation was first achieved in 1964 by S. H. Seal, who separated large tumor cells from the smaller blood cells using filtration. Two years later, Pohl and Hawk performed experiments on how cells respond differently to a nonuniform electric field based on the cell type. Such observations were the inception of cell separation methods, which allow isolating a single cell type from a heterogeneous sample.
