How do e-cigarettes affect neutrophils?

A new study published in the Journal Cell Physiology shows that e-cigarettes have toxic effects on neutrophils function, making them a threat to human health by increasing the likelihood of infection with Gram-negative bacteria. E-cigarettes are in wide use today, among 7% to 12% of adults and up to 37% of teenagers/new adults.

What is the purpose of vaping liquids?

The researchers used commercial vaping liquids and a commonly used vaping device to expose batches of neutrophils in culture to fresh puffs of e-cigarette vapor. They also injected Pseudomonas into healthy mice, exposed them to e-cigarette smoke over the long term and examined neutrophil migration as well as bacterial load.

How many fold reductions in chemotaxis in human neutrophils exposed to e-cigarette vapor?

Neutrophils in culture. The researchers found a 4-fold reduction in chemotaxis in human neutrophils exposed to e-cigarette vapor. Normally, their attraction to Gram-negative bacteria occurs in response to the cell wall component f-Met-Leu-Phe.

What is the role of e-cigarette smoke in the neutrophil attack?

They were also partially disarmed by e-cigarette smoke, which reduced reactive oxygen species (ROS) production within the immune cells by 48%. ROS are at the heart of neutrophil attack by what biologists call the neutrophil extracellular trap (NET). These fascinating antibacterial weapons are structures created from DNA strands coated with sticky proteins or peptides that fight microbes.

Is vaping safe?

Vaping – not a safe alternative. E-cigarettes have become a topic of hot controversy, with some people arguing their safety vis-à-vis conventional cigarettes, and others pointing out the almost complete lack of knowledge regarding the safety of inhaled chemicals in e-cigarette smoke, and their physiological effects.

Can e-cigarettes affect endothelial cells?

Their RNA sequencing studies on lung tissue from these animals also show that endothelial cells may be impacted by the e-cigarette vapor, such that they have a lower production of proteins that stimulate the passage of leukocytes out of the blood vessel into the infected site.

Is it safe to smoke e-cigarettes?

E-cigarettes are in wide use today, among 7% to 12% of adults and up to 37% of teenagers/new adults. While touted as a safer alternative to conventional smoking, evidence shows that they can be extremely harmful and in fact, lethal, as the recent spate of vaping-linked deaths in America shows.

How many pulls did the vaping experiment take?

These adults underwent only one session with their nicotine-free e-cigarettes, but it was a heavy one: Each person took 16 pulls lasting three seconds each. Doing so had three major effects on the artery and the blood that flowed through it.

Is vaping legal in 2019?

Vaping has already become one of the big public health stories of 2019. Illegal, unregulated vapes pose serious threats, and even legitimate vaporizer companies like JUUL and have drawn scrutiny from the FDAfor marketing their nicotine-heavy products to teenagers.

Does vaping affect femoral artery?

Doing so had three major effects on the artery and the blood that flowed through it. That heavy vaping session changed reduced the dilation of femoral artery by 34 percent on average — which means that it didn’t relax in response to an increase in blood flow as much as it did before the vaping session.

Does vaping increase pulse velocity?

The real metric that bolsters their argument was a change in aortic “pulse wave velocity,” which is essentially a way to measure how stiff an artery is. It’s also used to predict heart disease risk. After a session of vaping, pulse wave velocity increased by three percent, which “suggests acute arterial stiffening.” That’s not a great sign, though Wehrli adds that we still don’t know whether this would translate to prolonged stiffening with repeated use.

Does vaping reduce hemoglobin?

Finally, they found that vaping decreased hemoglobin saturation by 20 percent. Hemoglobin is the protein in red blood cells that carries oxygen, so this suggests that the blood was less oxygen-rich after a vaping session.

But the authors noted that during a normal vaping session, these chemicals probably wouldn’t reach high enough thresholds to be toxic.

Does vaping affect blood flow?

A paper published Tuesday in Radiology showed that even without nicotine, vaping flavored e-liquids caused significant changes in blood flow in the femoral artery, a major artery in the leg. Felix Wehrli, Ph.D., the study’s senior author, tells Inverse that these effects were temporary. But that’s not a reason not to take them seriously, especially for people who vape regularly (and even in 2018, record numbers of teens reported vaping within the last 30 days).

What is a vaping device?

Smoking e-cigarettes is often referred to as “vaping.” E-cigarette devices use an electric battery to change a liquid solution containing nicotine into a vapor that can then be inhaled. About 7 to 12% of U.S. adults use e-cigarettes, as well as up to 37% of adolescents and young adults.

Is there research on cannabis and the immune system?

Research on cannabis use and the immune system in the general population is scarce (Friedman et al., 1990; Rajavashisth et al., 2012 ). The 2018 report of the National Academies of Sciences, Engineering and Medicine identified the lack of studies on cannabis use and immunity in healthy individuals as a research gap (National Academies of Sciences, 2017 ).

Does cannabis affect neutrophils?

Positive associations between heavy cannabis use, and total WBC and neutrophil counts were detected. Clinicians should consider heavy cannabis use in patients presenting with elevated WBC count. Research on heavy cannabis use and cardiovascular health is needed as systemic inflammation, increased cardiovascular risk and increased mortality risk have been all associated with WBC elevation within the normal physiologic range (Lee et al., 2001 ). Additionally, studies with repeated measures are needed to study immunomodulatory changes in cannabis users, and whether the mode of cannabis use can differentially affect immune responses.

Does cannabis lower immune system?

Conversely, studies in adolescence and young adults indicated that cannabis use is not associated lowered immune responses (Ferguson et al., 2019; Costello et al., 2013 ). The reported anti-inflammatory effects of cannabis were greatly attenuated when body weight is controlled for. This suggests that the inverse cannabis-body weight association might explain the lower levels of circulating inflammatory biomarkers in adult cannabis users (Penner et al., 2013; Le Strat and Le Foll, 2011; Alshaarawy and Anthony, 2019 ), given the strong association of inflammation and adiposity (Esser et al., 2014 ). The results of the current study indicate elevated WBC count among heavy cannabis users, and persisted after adjusting for BMI. This increase might be related to the inflammatory effects of combustion by-products as the most common mode of cannabis use is smoking (Grotenhermen, 2003 ). The association of cannabis and WBCs was evident in heavy users only, which might indicate increased exposure to proinflammatory chemicals generated from smoking (Wei et al., 2016 ).

Does cannabis increase WBC?

These alterations of immune responses by cannabis use might be associated with increased susceptibility to infections and hence the higher WBC count. Indeed, Tsai et al. have reported an association between regular cannabis use and suboptimal self-rated health status, independent of tobacco smoking (Tsai et al., 2017 ). Yet, it is possible that the elevated WBC and suboptimal health status contributed to cannabis use rather than cannabis use caused suboptimal health. This hypothesis, though, cannot be tested as NHANES does not collect information on cannabis use motives. Another potential mechanism can be through the effect of cannabinoids on stem cells. Pre-clinical studies suggest that cannabinoids stimulate hematopoiesis (Valk et al., 1997 ), and hence this stimulation to bone marrow tissues can be associated with increased circulating WBC count in cannabis users.

Why does my WBC count drop?

Spleen problems: The spleen also makes WBCs. Infections, blood clots, and other problems can make it swell and not work the way it should. This will drop your WBC count.

Why is my WBC low?

Low WBC counts are often linked to bone marrow problems. Being around certain chemicals, like benzene and pesticides, as well as some types of cancer and cancer treatments including chemotherapy and radiation, can hurt your bone marrow's ability to make WBCs.

How many white blood cells are there in a microliter?

How many white blood cells (WBCs) someone has varies, but the normal range is usually between 4,000 and 11,000 per microliter of blood. A blood test that shows a WBC count of less than 4,000 per microliter (some labs say less than 4,500) could mean your body may not be able to fight infection the way it should.

What diseases will tell your body to attack and destroy its own WBCs?

Autoimmune disorders: Some autoimmune diseases, like lupus and rheumatoid arthritis, will tell your body to attack and destroy its own WBCs.

Does benzene harm white blood cells?

Scientific American: "Even at Low Levels, Benzene Takes Toll on White Blood Cells."

Does HIV kill WBCs?

HIV kills a specific kind of white blood cell. Medicines: Some drugs, including antibiotics, can destroy WBCs. Nutrition: Not eating well or low levels of certain vitamins, such as folic acid and B12, can affect how your body makes WBCs . Alcohol abuse can mess with the nutrients in your body and with WBC counts, too.

Is there a normal range for each of the five types of WBCs?

This other test gives a lot more detail. There are normal ranges for each of the five kinds of WBCs, and some problems only affect one type. The results of a diff could help your doctor narrow down what's going on.

Does smoking increase white blood cells?

Passive tobacco cigarette smoking caused a significant increase in white blood cell count, lymphocyte count and granulocyte count for at least one hour ( P < 0.05; Fig. 1 ), whereas the rest of the CBC indices studies did not show significant changes.

Does smoking affect CBC?

Our results suggest that active e-cigarette smoking in smokers and passive e-cigarette smoking in never smokers do not affect markers of CBC. In contrast, active tobacco cigarette smoking in smokers and passive tobacco cigarette smoking in never smokers increase white blood cell count, lymphocyte count, and granulocyte count for at least one hour. The results on active tobacco cigarette smoking are in line with published evidence showing an increased number of leukocytes and granulocytes following acute smoking ( Hockertz et al., 1994, Morrison et al., 1999, Winkel and Statland, 1981 ). With respect to passive tobacco cigarette smoking, some ( Panagiotakos et al., 2004, Ronchetti et al., 1990 ), but not all ( Husgafvel-Pursiainen et al., 1987, Sochaczewska et al., 2010, Venn and Britton, 2007 ), studies suggest that chronic exposure to passive tobacco cigarette smoking leads to increased white blood cell count. The systemic inflammation observed following acute passive tobacco cigarette smoking is also in line with results from the main proteins of acute inflammatory load. Specifically, interleukins 4, 5, and 6 as well as interferon gamma show a prolonged increase following tobacco cigarette smoke inhalation ( Flouris et al., 2009 ), while levels of C-reactive protein are higher in individuals passively exposed to tobacco cigarette smoke on a daily basis ( Panagiotakos et al., 2004 ).

What are the effects of e-cigarettes?

Exposure to the e-cigarette flavoring chemicals and e-liquids led to higher production of two well-established biomarkers for inflammation and tissue damage mediated by oxidative stress. Furthermore, many of the flavoring chemicals caused significant cell death -- with some flavors being more toxic than others.
