Secukinumab, an anti-interleukin-17A monoclonal antibody, has successfully completed multiple clinical trials, which found the intravenous treatment may be safe and effective for treating patients with active ankylosing spondylitis…
Lara C. Pullen, PhD, is a medical writer with a PhD in microbiology/immunology from Northwestern University’s Feinberg School of Medicine. As a medical writer she has covered topics as diverse as diabetes, cardiovascular disease, and autism. Her favorite subject, however, is the role of the immune system in health and disease. Dr. Pullen is also the mother of three children, the youngest of whom has Prader-Willi Syndrome (PWS). She is an active member of the PWS community and a thought leader on the importance of the ketogenic diet for this patient population.

Insight into Crosstalk Between Bone & Immune Systems
Osteoimmunology is an emerging field that focuses on the interaction between bone and the immune system. CD4+ T cells play an important role in the bone marrow and modulate the differentiation of bone-resorbing osteoclasts. This article reviews the role of CD4+ T cells as an osteoclastogenic population in inflammatory bowel disease…
Study Targets Osteoclast Receptor to Inhibit Osteoclastogenesis
The results of a new study examined the human osteoclast-associated receptor may aid in the development of therapeutic matrikines to control aberrant osteoclastogenesis in some autoimmune diseases…
Gut-on-a-Chip Provides Insight into Microbiome & Intestinal Inflammation
Researchers have created a microdevice with Caco-2 intestinal epithelial cells to aid in studying the human gut microbiome’s role in homeostasis, immune modulation and pathology. Using this gut-on-a-chip, researchers were able to examine in detail the processes they think result in chronic intestinal inflammation…
Researchers Target Altered T Cell Metabolism in SLE to Reverse Lupus Immuno-Phenotype
A recent study on systemic lupus erythematosus examined the effects of metabolic modulators on the disease’s abnormal T cell metabolism. Using a combination therapy of metformin and 2-deoxy-D-glucose, researchers were able to normalize CD4+ T cell functions and restore defective IL-2 production in mice…
Large Group Study of Systemic JIA Patients Provides Insight into Disease Pathology
In a large group genetic analysis, researchers identified an association between the class II HLA region, including HLA-DRB1*11, and systemic juvenile idiopathic arthritis (sJIA), implicating adaptive immune molecules in sJIA’s pathogenesis and reinforcing its unique genetic position among JIA subtypes…
Study Uncovers Tet2’s Role in Resolving Inflammation
When investigating the role of epigenetic modifiers in inflammatory response, researchers found that Tet2 acts at the chromatin level to help resolve inflammation in both dendritic cells and macrophage, repressing the transcription of IL-6…
ACPA-Positive & ACPA-Negative Patients with RA: The Difference Begins in the Lungs
A new study from Stockholm, Sweden, strengthens the link between the lungs and anti-citrullinated protein antibody (ACPA)–positive RA. After analyzing the bronchial tissue of untreated patients with early RA, researchers found the patients’ lungs had signs of immune cell accumulation and activation…
New Evidence MRI Can Be Used to Monitor Neuromuscular Disease Progression
In a study of patients with Charcot-Marie-Tooth disease, researchers found that MRI scans can be used to detect the muscle water changes that precede marked intramuscular fat accumulation that may contribute to the disease’s presentation. MRI biomarkers may prove useful in clinical trials for therapies for this and other neuromuscular disorders by enabling researchers to measure disease progression…
Gene Expression Markers in T Cells Help Identify SLE Patient Subtypes
Researchers used T cell transcriptome analysis in a small-scale study, identifying gene expression of specific patient subtypes and finding that expression alteration of T cells may correlate with severity of SLE rather than its presentation…
