How strong is a bat s immune system?

Its tiny body is simply oneLarge virus reservoirs, including the rabies virus, more than 100 viruses are gathered in one, like a living biochemical**. In the highly dense social state and long-distance flight process, the bats communicate with each other, realizing the collection and distribution of the virus. And because of its special immune system and DNA repair ability,The bats themselves are invulnerable.

In the early days of the 2019 novel coronavirus epidemic, the research team obtained the whole genome sequence of the virus from five patients, and after studying, the genomes of these five cases were basically identical, and the consistency with the SARS-related virus sequence was as high.

Moreover, the research team found that the novel coronavirus had a sequence identity of up to 96% with a coronavirus in a type of bat. This shows that the natural host of the novel coronavirus in Wuhan is likely to be bats.

In recent years, the white-nosed syndrome has led to the extinction of bats in Europe and the Americas.

Why do some people still boast that bats are almost invincible in immunity?

First of all: bats are the source of infection for many viruses, and they cannot get sick. This is because bats, as an ancient population, are alien to most organisms on the earth, and there is no virus circulation but carrierability, just like humans can carry chicken plague but do not cause disease, that is because the biological mechanism of humans and chickens is completely different.

The strategy of the virus is to be the majority of the population, and the bat, as an ancient creature, only acts as carriers, while the virus targets other mammals.

Second: bats are the only animals in the world that can regulate their own body temperature (, most of the world's mammals will lose their activity if they are more than 40 or 20 or so, but they will survive, so that bats can only carry but do not cause disease, and the virus that causes bat disease will also not be transmitted to humans.

In summary, bat body temperature is responsible for the fact that bats are carriers of most viruses, rather than having a strong immune system.

So why are there so many brainless blows?

First of all, contemporary medicine has been slow to develop for the sake of economic efficiency, and many people have shifted from actual research to hunting for curiosities to raise awareness.

Second, bats as a mysterious creature have survived on Earth for tens of millions of years, as if as a symbol of health.

To sum up, the immune system of bats can only be used to brag and earn traffic. It would be a fool to believe that there is practical value in studying the immune system of bats.

Bats have SARS-like viruses on them.

There are more than 10 kinds of viruses such as rabies virus and Nipa, which are the most important new viruses in the world in the past ten years; In addition, it has some unknown new viruses on it.

Bats do not become ill themselves, but the virus they carry causes extremely high mortality rates in humans and animals. "If the immune system of bats can be cracked, it will have a huge impact on the entire virology, human medicine, and ecological environment. ”

Why did bats become the "king of drugs"? Wang Linfa believes that there are two possibilities, one is that bats are the most numerous mammals in the world.

1. Category.

Second, it is the most widely distributed; The second is that bats, as the only mammals that can fly, may have been evolutionarily separated from other mammals a long time ago, so they have hitherto unknown characteristics.

Please see for details.

Due to the large energy consumption of bats when flying, especially most insectivorous bats are small, metabolize quickly, dissipate heat quickly, and consume energy faster, so bats usually enter a deep sleep state during the day, reducing body temperature and metabolism to reduce energy consumption. Therefore, their chosen daytime habitat, whether it is a cave or a crack in a house, must maintain a specific temperature and humidity. Studies have shown that changes in air flow, temperature and humidity and noise, as well as when people enter and exit the burrow, can disturb bats and make them have to increase their metabolism to cope with these changes, regardless of whether they will fly out of the burrow or stay in place.

Some species of bats migrate to specific locations for the winter when the temperature drops and the amount of food drops sharply in autumn, while others hibernate in or near the habitat where they are young, and a few species maintain their activities and barely survive on the scarce insect resources in winter. Usually, bats spend the winter looking for a place with less disturbance and low temperatures, so that they can reduce their body temperature and metabolic rate, and save energy consumption. Bats that are hibernating or spending the winter are in a state of physiological urgency, and it is extremely difficult to maintain an energy balance.

Any disturbance may cause it to have to wake up with energy; Excessive energy overdraft and food shortages can easily cause them to be unable to support the next spring and lead to death, so hibernation is the most sensitive and vulnerable time for them.

There is a limit to the number of points that can be added, and it is not possible to add 200 points.

In fact, it is not that bats have a strong immune system, but that they reproduce quickly, and after many generations of heredity, they have immunity to early viruses, just like humans are now immune to many viruses, and there is genetic accumulation.

From an evolutionary point of view, many bats died in the early stages of the virus mutation, and some survived. The offspring have immunity. In the animal world, there are many similar examples of immunity to a virus.

Our immune system is triggered to turn on, and bats' immune system is always on alert. I looked up the information about bats.

First, the peculiarities of bats

Bats can be described as an outlier among mammals, which do not conform to the habits and laws of normal mammals. For example, a heartbeat. According to scientific studies, in general, the more the mammalian heartbeats per minute, the shorter the animal's lifespan.

For example, a rat's heartbeat is about 480 beats per minute, and the lifespan of a mouse is three years, and an elephant's heartbeat of 26 beats per minute is about 60 years. However, bats have a lifespan of up to 30 years, and their heartbeats can reach about 800 beats per minute.

Second, the body temperature of bats

We all know that when the human immune system is fully open, it will have a fever and kill the virus at the cost of a persistent high fever, but we humans can't stand the high temperature for a long time, so if the virus is not eliminated, people may die. For example, when the major viruses facing mankind attack, there will be a rise in body temperature, such as the Ebola virus, the SARS virus, and the new coronavirus that we are currently facing in China. Interestingly, bats also maintain a normal body temperature of around 40 degrees, which would make the virus not survive in general.

Third, bats and viruses

Many of the viruses that are rampant in us humans have been brought by bats after investigation. And this time the new coronavirus**, some scientists also published that once it was bats brought to wild animals, and wild animals gave it to us. However, because the immune system of bats is always fully open, and their body temperature can be maintained at very high temperatures, most viruses cannot do anything about them, and they are like a mobile virus reservoir.

Especially the bats that remain now have survived the attacks of deadly viruses again and again, and the so-called superior survives.

What do you think of bats?

The immune system of a bat is very strong, its body can be immune to countless viruses, and it can also store countless viruses, and it is impossible for humans to have the same immune system as bats.

The body temperature of bats is higher than that of humans, and it can withstand temperatures of 40 degrees, so the virus cannot survive in its body, and the immune system is stronger than that of humans.

The components of the bat innate immune system are the same as those of other mammals, including interferon, interferon-activating genes, and natural killer cells. The components are the same, but the performance in the face of deadly viruses is different, suggesting that the bat innate immune system may have peculiarities in molecular function and regulatory expression.

The immune system of bats can provide clues on how to avoid certain infectious diseases, and the presence of antibodies in the blood of bats can prevent the occurrence of various diseases. This animal lives in the wild for a long time and naturally has a higher immunity. Comparatively speaking, our human immune system is much more fragile and has not evolved so many antibodies.

The body temperature of a bat is different from that of a human. The body temperature of bats can reach more than 40 degrees. Many viruses and bacteria cannot survive in environments above 40 degrees Celsius.

The fact that bats, which have a lot of viruses in their bodies, have survived until now has something to do with their strong immunity, but it has more to do with genetics。In fact, bats do not mean that they can be immune to these viruses from the beginning, but because bats reproduce very quickly, so in the process of genetic reproduction, those genes that cannot withstand these viruses are all dead, and those who can survive now are bats that have immunity to these viruses.

In fact, the same is true for human beings in the process of evolution, before human beings were not resistant to many viruses, in ancient times, viruses that may seem very inconspicuous now can cause hundreds of thousands of deaths. But with evolution and reproduction, humans have now developed resistance and immunity to many viruses, and this is because of the accumulation of genetic processes.

So bats are now able to live in symbiosis with so many viruses, in fact, because of evolution. If the bats could not adapt, the bats might have become extinct many years ago, in fact, this confirms the truth of "natural selection, survival of the fittest". At the same time, bats consume a lot of energy in the process of flying, because the body temperature of bats is usually kept at a relatively high temperature.

However, the virus cannot be transmitted and survive in a continuous high temperature environment, so it also reduces the pathogenicity of many viruses. Of course, bats deal with so many viruses every day, and have developed immunity to these viruses over a long period of evolution. However, the human body is not resistant to these viruses, so once infected, the disease will break out.

Although these viruses exist in the body of bats, they do not pose any threat or harm to the bats themselves, but if they are encountered by organisms or humans who are not resistant to these viruses, then they may cause damage to the immune system and lead to infection. However, bats have long been able to live in symbiosis with these viruses due to their evolutionary years, so they have no effect on them.

The reason why bats, which have a lot of viruses in their bodies, have been able to survive until now is because they have been dealing with viruses for a long time, so their immunity will be relatively strong.

When we encounter a virus in our body, there will be cells to kill the virus, so that many of our cells will die, which will affect our health, and bats will live in peace with him after encountering the virus, so there is no harm to bats.

Although bats have a lot of toxins in their bodies, because bats themselves are immune to these toxins, they can survive so many viruses.

It is because of his strong immunity, which is very powerful, which can allow so many viruses to exist together, and it will not cause him a little harm.

It has nothing to do with the immunity of bats. Viruses in bats. It only has an effect on the human body. No matter how many viruses there are. Doesn't work on bats either. Bats are just the reservoir for the virus.

No, the immunity of bats is not very strong, and the immune response such as redness, swelling, heat and pain is not particularly severe. The reason why so many viruses in the body can survive is that the temperature is relatively high, and secondly, because of its ability to remove waste. What's more important is its powerful DNA repair ability.

Bats are immune to all viruses, but other organisms are not immune, because bats have been able to live with viruses after tens of thousands of years of continuous evolution, and other organisms have not undergone this process, so they cannot be immune.

Bats are immune to all viruses, and I personally think that other organisms are not immune, because the characteristics of each organism and animal are different, so I personally think that bats are immune to all viruses, and other organisms may not be immune.

No, bats are immune because they have toxins in their bodies, while other organisms don't, so other creatures are not immune.
