The 's Innate Immunity Of A Patient

A T cell are also referred to as T lymphocytes which are key cells of specific immunity as referenced by Krasner and Shors.

The type of responses and characteristics differentiate acquired immunity from innate immunity. Acquired immunity is a slow response as it focuses on the specific antigen. It has a memory and therefore can recognize similar antigens that entered the body and to implement the appropriate immune response. The acquired immunity secretes antibodies and molecules that recognize specific antigens. Innate immunity on the other hand is not specific to the type of antigen as it has no memory. Since it is not antigen specific, it provides a faster response to antigens, but it does not tailor the response to the type of antigen. Innate immunity includes physical barriers such as the skin and it recognizes foreign antigens based on patterns.

In the bloodstream, a very small number of tumor cells survive to reach the target organ, indicating that metastasis formation must be regarded as a very ineffective event [7,8]. Millions of carcinoma cells enter into the circulatory system, but the majority of them die during transportation, and only 1-5% of viable cells are successful in formation of secondary deposits in distinct sites [7-9]. It is known that many cells of the immune system, such as NK cells, macrophages and lymphocytes, could contribute to the elimination of tumor cells in the vascular

Scientists discovered two very important facts about the tumors themselves that explain the malfunction of NK cells. The first one is that an inflammatory

It is therefore unsurprising that an increasing amount of research is being carried out on immunological approaches to cancer treatment, which is inherently more specific, targeting malignant neoplastic cells which may display a specific stress marker, opposed to general cellular destruction, and which carry a significantly lower risk of short and long-term secondary health risks and side effects.

Immunotherapy is a whole new way of tackling cancer (para7). It is a combination therapy that helps the body’s own defenses fight cancer cells (para 1). Immunotherapy tricks the body’s defenses into fighting cancer. There is evidence that it can halt sometimes terminal cancer in its tracks (para3). Trials involving a combination of immunotherapy drugs for skin cancer were impressive (para4). Half the patients in the trial that were considered terminal ill responded to the combined drugs in fifth of the patients, and it shrank the tumors in 58% of patients (para5). Combining treatments also increase the likelihood of potentially severe side effects (para 11). The hope is that the therapy may be able to teach the body’s immune system to recognize

Radiotherapy, chemotherapy, and other highly invasive techniques (such as surgery) are extraordinarily toxic mechanisms employed to attempt the removal or reduction of cancerous tumours and growths. Such procedures are comparably barbaric to current research areas regarding immunotherapy and targeted therapies, aiming to enhance and harness the body’s natural immune antitumour response by overwhelming tumour immune evasion and suppression mechanisms [8].

During evolution process, most organisms have established a sophisticated immune system to protect and clear the invading pathogens. The immune system of vertebrates has been divided into innate and adaptive immune system, although, emerging evidences have shown the interplay between the two. The innate immune system comprises physical barriers, cellular components and humoral responses that can be activated in the early phase of infection upon interaction with foreign antigens as immediate response against them and further helps to shape adaptive immune response on the basis of the nature of stimulant by activating the components of the adaptive immunity. The vertebrate innate immune system relies on pattern recognition receptors

This original research focuses on defining cancer immunotherapy and the different types of immunotherapy that has received regulatory approval within the past twenty-five years. Cancer immunotherapy also known as biotherapy is "the manipulation of the immune system, or utilization of components of the immune system, as the cancer treatment." After a brief history of immunotherapy and the foundation of its origin is given in the introduction Dillman goes into detail about the different types of immunotherapies. The different types of immunotherapies include nonspecific immune stimulants Bacillus Calmette-Guerin (BCG) and Levamisole which are drugs used to boost the immune system in a general way. Cytokines are the messengers of the immune system; interferon-a and interleukin-2 are cytokines used to mediate and regulate immune responses, inflammation, and hematopoiesis which is new blood cell formation.

Since the discovery of cancer cells, doctors have focused on destroying malignant cells. When cancerous cells invade healthy cells, the infection can suppress the immune system. The organs and tissues are deprived of oxygen, and the radical changes cause the cells to behave abnormally.

Age specific variations of growth and development. For children ages three to five years immunization status is necessary. The Nursing care of Infants and children, has recommendations for routine immunizations. Preschoolers should have already been administered their Hepatitis B, Hepatitis A, Measles, Mumps, Haemophilus influenza Type B, pneumococcal disease, and meningococcal disease. (Hockenberry, Wilson, 2015, p.202-205) Three to five year olds should be administered the pertussis vaccine, four doses of Polio at 2 months, 4 months, 6-18 months , and 4-6 years of age,” (Hockenberry, Wilson, 2015, p.202) Rubella, the second dose of Varicella, and the annual influenza shot. (Hockenberry,

Being diagnosed with cancer may be one of the most difficult tasks someone could go through. How are they supposed to react? Are they supposed to cry, sit in awe, or be angry? Coping with news like this can be difficult. Not only that, but it could cause so many problems throughout their life. It could cause much more than health issues, but there is also the emotional state of someone’s well being.

The immune system is a complex network of innate and adaptive compartments that work together in order to protect and fight against pathogenic invaders. The immune system also acts as a regulator of host homeostasis in order to ensure that the body is operating under optimal conditions. The composition of microbiota is associated with the adaptive and innate immune systems, which work together in order to maintain a constant relationship between the increasingly different microbiota and pathogens found within our body.

Cancer has been ascertained as a leading cause of morbidity and mortality among individuals worldwide. It occurs in the body when cells grow uncontrollably and no longer die. In regular cells a programmed cell death called apoptosis will occur before a neoplasm can be formed; however in carcinoma cells, this programmable cell death is broken and invasive, metastatic tumors can form. Metastatic tumors are cancer cells that have spread throughout the body using the bloodstream making detection even more difficult and potentially lead to death [1]. These cancer cells can interfere with normal functioning cells by up taking nutrients and resources by invading into the normal cells and tissues; this development is called metastasis. Death

Zinc is the 24th most abundant element in the earth’s crust, it is a metallic chemical element which has “exceptional biological importance” (Bonaventura et al., 2015). Zn is involved in numerous aspects of cellular metabolism such as: protein synthesis, cellular respiration, wound healing, DNA synthesis, cell division, and immune function (Bonaventura et al., 2015). For as many essential functions Zn is necessary for it also has the potential to interact with at least as many biological functions to induce adverse effects (Maret and Sandstead, 2006). For these reasons Zn deficiency and toxicity is linked to a number of diseases and particularly immune diseases affecting both the innate and adaptive immune systems (Bonaventura et al., 2015, Maares and Haase, 2016).Therefore, a disruption in Zn homeostasis can lead to compromised host defense and an increased risk of excessive inflammation (Maares and Haase, 2016).
