As a result, live bacteria are present inside the immune cell for up to 24 hours. H. pylori defends itself by causing the vacuoles in which it is engulfed by the macrophage to fuse together, generating one large vacuole inside of the macrophage that contains many bacteria. These large vacuoles are less efficient at killing bacteria than are numerous small vacuoles. In this way, the bacteria are able to delay being killed. It is unclear whether these bacteria later escape back into the tissue, but the fact that they can survive for several hours suggests that this is a potential reservoir of re-infection.

Another hiding place for H. pylori is in the epithelium. H. pylori lives within and beneath the mucus layer of the stomach, and a fraction of these organisms (around 10 percent) actually attach to the epithelial cells. This close association often leads to the bacteria being taken into and between epithelial cells. This is beneficial for the bacterium in several respects. Because the immune system is extremely well trained to avoid killing host cells, H. pylori can avoid attack by hiding inside them. In addition, using an antibiotic as an h pylori treatment as well as other harmful substances that might be present in the stomach are not as effective at reaching the bacteria when the organisms are enclosed within the epithelial cells. Furthermore, internalized bacteria avoid being washed away when the stomach empties its contents into the duodenum. In spite of the advantages of life inside the epithelium, however, the majority (90 percent or more) of H. pylori organisms in an infected animal or human appear to be free-living in the stomach, rather than epithelial cell parasites. H. pylori expresses them to trick the immune cells into thinking that the bacteria cells belong to the host. Because the immune system is very careful about turning its weapons upon itself, it is prevented from initiating attacks against the disguised bacteria.

This camouflaging process is a controversial topic, however, as immune reactions do occur as a result of other activities that the bacteria perform, and because other notions about the function of this protein have been suggested. Since the receptor for Lewis antigens is also expressed on the surface of the stomach’s epithelial cells, it has been suggested that the real function of this protein is to serve as an anchoring point for the bacterium. Only a minority of the germs (around 10 percent) actually attach to the epithelium, while the remaining 90 percent are distributed throughout the mucus layer. Thus, it has been argued by some scientists that the Lewis Blood Group proteins are more useful in allowing the bacteria to avoid attack by the immune system than in helping them adhere to the epithelium. Additional work on this subject will undoubtedly reveal more about the function of these proteins in the life cycle of the organism.

There are a number of reasons why cellulite can affect some women and not others.

Diet and Lifestyle

Cellulite wasn’t a problem for women in the 1950s and 1960s because their diet and underwear were different. If you do a lot of traveling to developing countries, you will notice that cellulite doesn’t affect the locals unless they are consuming a Western-style diet.

Furthermore, underwear in these days didn’t have elastic bands. Today’s underwear do and this band cut circulation off to the skin of buttocks and thighs. A good idea for cellulite prevention is to wear a thong.

Muscle vs Fat

Research has shown that cellulite can occur when there is an imbalance between the muscle and fat on the legs and buttocks. The more muscle you have the more defined, smoothed and tight the area will be. Some skinny women have cellulite because they have a lack of muscle, not because they have too much fat. You can either use strength training to increase lean muscle mass or a new treatment called Ionithermie cellulite reduction therapy.

Genetics

The final nail in the coffin is genetics. You either susceptible to the condition or you are not. While you can’t change your genes, you can influence how they get turned on through avoiding the lifestyle risk factors or undergoing anti cellulite treatments.

Why Do You Have Cellulite?

If you were to take a look at photographs of women on the beach in the 40s, 50s and 60s, you would notice many full figured women who showed no signs of cellulite. In the decades that followed, women’s diet and environment changed so that they increased their likelihood of developing cellulite. Here are the main factors that have caused this change.

Hormones: science has shown that the main cause of cellulite is estrogen. Medications, food and the contraceptive pill are all factors that can increase the production of estrogen and influence the severity of cellulite that a woman experiences.

Skin cream: lotions that contain mineral oils are known to block the ability of the skin to absorb healthy nutrients. Without these nutrients, toxins and fluids build up in the fat cells worsening the cellulite.

Fat: the wrong types of fat can cause an increase in weight gain and cause an increase in cellulite. In contrast, the right types of fat can actually help combat the condition.

There are number of treatments that can target these factors. These remedies include Ionithermie cellulite reduction, anti cellulite creams, massage and exercise. Spend some time talking to your local beautician and they will be able to advise you on the best treatment for you.
