Removal of B1b B cells protective against lupus

Systemic lupus erythematosus (SLE), commonly known as lupus, is an autoimmune disease with no cure. Monash researchers have been working to understand the immunological causes of lupus in a mouse model so as to better understand the disease in humans. Such groundwork will enable the development of much more effective therapies for the treatment of lupus.
Professor Fabienne Mackay (former head of the Department of Immunology and Pathology), together with the department's Leukocyte Signalling laboratory headed by Associate Professor Margaret Hibbs have discovered that a certain type of innate B cell (immune cell), known as a B1b B cell, may be critical in the development of lupus.
Two types of mature B cells that are activated by toll-like receptor (TLR) signalling are B1 B cells and marginal zone (MZ) B cells. In the mouse model studied, these cells cause disease by infiltrating various tissues such as the salivary glands and kidneys. When the MZ and B1a B cells were removed from the mice, disease still occurred. When B1b B cells were removed also, mice were protected from all symptoms of lupus. Therefore B cells and CD19 signalling, specifically innate B cells, are very important in the development of lupus and may represent a target for treatment.

New gene mutation identified in Bernard-Soulier syndrome patient
By Dr Jodie Abramovitch
Bernard-Soulier syndrome (BSS) is a rare condition in which blood does not clot properly leading to increased bleeding. The underlying
cause of this condition is due to a defect or deficiency in a specific receptor found on platelets
(component of blood that aids blood clot formation) called GPIb-IX-V. This particular receptor controls platelet adhesion, allowing
them to ultimately form a clot and thereby prevent excessive bleeding.
Dr Elizabeth Gardiner and A/Prof Robert Andrews |
Monash researchers from the Australian Centre of Blood Diseases in the Systems Haematology group, led by Associate Professor Robert Andrews and Dr Elizabeth Gardiner, and collaborators from the Alfred Hospital and the Kolling Institute of Medical Research (Sydney) have identified a new gene mutation in platelet receptor component GPIbβ
in a patient with BSS. The patient had a greatly reduced number of platelets
in the blood and a clinical history of mild bleeding.
Upon closer analysis of the patient’s platelets, a number of important platelet molecules were found to only be expressed at very low levels or were undetectable. Another molecule that assists with receptor organisation, called CD9, was also found to be reduced.
Upon closer analysis of the patient’s platelets, a number of important platelet molecules were found to only be expressed at very low levels or were undetectable. Another molecule that assists with receptor organisation, called CD9, was also found to be reduced.
They discovered that this patient had a previously
undescribed genetic mutation in GPIbβ that was interrupting the formation of important platelet
receptors. This led to platelets that were unable to clot together properly,
resulting in a longer bleeding time.
The link between mutated GPIbβ and reduced CD9 is unclear
though has been previously reported in other BSS patients. As such, CD9 may be
a new marker to help definitively diagnose BSS patients.

The Director and Head of the Allergy, Immunology and Respiratory Medicine department in The Alfred and Monash University, Prof Robyn O'Hehir said peanut allergy is a rapidly growing problem in Australia and around the world.
This new investment from the Brandon Capital managed Medical Research Commercialisation Fund, together with the support of an additional $1.44M National Health and Medical Research Council grant (announced in November), will ensure Prof O'Hehir and her team at The Alfred and Monash University can continue the research effort that she began close to 15 years ago.
