Description

Studies have found a link between lupus and a group of genes known As Major Histocompatibility Complex ( MHC) genes. MHC genes provide the following functions:

• Enhancing the immune system's reaction to specific infectious pathogens

• Producing a type protein that's associated with the immune system's inflammatory response

Lupus is also linked to several additional genes that interact with MHC genes and the immune response. They offer cells instructions to make proteins which deal with:

• Signaling to the immune system

• Identifying and adhering themselves to infectious organisms

• Impairing the function of immune system cell receptors

• Function and growth of B-cells and T-cells (white blood cells vital for immunity) and specific antibodies

• Cytokine secretion by inflammatory cells

• Production of specific autoantibodies, including anti-Ro and anti-La antibodies

• Higher levels of immune system activation

Some of the proteins related to these genes have been linked to a variety of autoimmune and inflammatory illnesses and may be used as biomarkers for these conditions, including:

• C-Reactive Protein (CRP)

• TNF-

• IL-10 (interleukin 10)

Each of these genetic disorders affects cells, receptors, and chemicals in your immune system, which contributes to lupus autoimmunity. Because several of these characteristics are additionally involved in additional autoimmune conditions, It shows why there are so many multiples.

Monogenic lupus

The majority of lupus cases are thought to be attributed to changes in numerous genes (called polygenic), although others are thought to be caused by single mutations (called monogenic).

While SLE can be caused by a variety of genes, the most frequent single-gene mutation is known as a complement deficit.

After the immune system initiates an attack, a set of proteins known as complement proteins do a vital clean-up work. Because of the insufficiency, this clean-up is ineffective, leaving behind networks of chemicals that might harm the tissues Complement proteins may potentially aid in cytokine generation.

A mutation in the PRKCD gene (for protein kinase c-) is another monogenic cause. This mutation causes an overabundance of Tcells and causes B-cells to transmit incorrect signals to the body's immune system.

A few additional known mutations are thought to be responsible for monogenic lupus. Whatever the source, the final outcome is organ autoimmune activity. Monogenic lupus is regarded to be uncommon and is distinguished by the following characteristics:

• Early development, usually before age

• Greater disease severity

• Kidney damage

• Central nervous system association

Epigenetics

While genetic changes appear to be crucial in the emergence of SLE, experts feel they may not tell the entire story. This notion is based in part on studies among identical twins. When one of the twins has the condition, the other has a less than 60% chance of getting it as well. The proportion would be larger if it were genuinely genetic.

Because over 40 percent of identical twins do not acquire lupus while their twin does, a different kind of genetic influence--which occurs after birth--is most likely at work here. This genetic effect is referred to as epigenetics.

Genetic mutations are present at birth, but epigenetic modifications can occur throughout the lifespan and are impacted by environmental variables (such as contamination or infections) or factors related to lifestyle (such as nutrition and smoking). The DNA itself does not change, but certain components can be turned "on" or "off" so one's genes deliver different instructions to the cells.

According to research, multiple epigenetic pathways are at working in lupus, including:

• T-cell and other important immune cell gene overexpression

• Cytokine-associated gene alterations

• MicroRNA changes associated with kidney and systemic immune function

Some epigenetic modifications have been proposed as biomarkers to aid in the diagnosis of lupus, monitoring disease activity, and assessing the risk of damage to organs.
