A 30-year-ol of HIV with a CD4 cell count of 120 cells (normal, 1000–1500). He had an ulcerating lesion on the side of his tongu

HIV is the human immunodeficiency virus. Causer of AIDS, it attacks the immune system, responsible for defending the body from diseases. The most affected cells are CD4+ T lymphocytes. And it is by altering the DNA of that cell that HIV makes copies of itself.

<h3>1. Discuss the pathophysiology of HIV in relation to the reduction of CD4 cells</h3>

HIV binds to a component of that cell's membrane, CD4, penetrating its interior to multiply. As a result, the defense system gradually loses the ability to respond properly, making the body more vulnerable to disease.

<h3>2. Discuss the body's immune response to the virus (HIV)</h3>

The innate immune responses to HIV infection are mainly the intense production of cytokines, such as interleukin (IL)-1 and interferon (IFN)-1, and the activation of natural killer (NK) cells, which can temporarily control HIV replication. through apoptosis of infected cells

<h3>3. Explain the molecular and cellular immune response that leads to the swollen lesion.</h3>

due to the accumulation of primary immune cells and the body's long attempt to fight the infection

<h3>4. Discuss the cellular and molecular immune response that results in enlargement of the spleen and cervical lymph nodes</h3>

An infection from bacteria and viruses, including HIV, can cause swelling of the lymph nodes. The swelling occurs because the infection reaches the nodes through lymph fluid. HIV most often affects lymph nodes around the neck as well as in the armpits and groin.

Most children with cystic fibrosis have frequent lung infections and digestive difficulties. Some people have mild cases, with o

hram777 [196]

Answer:

The correct answer is 4: "The exception to Mendelian laws of inheritance that best explains the mentioned symptoms is codominance".

Explanation:

In codominance, both alleles can be expressed. In these cases, heterozygote individuals<em> instead</em> of showing an <em>intermediate phenotype</em>, express both of the alleles. Their phenotype is an additive expression of their parents' genes.

In cystic fibrosis, there is a gene responsible for coding for a protein named "cystic fibrosis transmembrane conductance regulator, CFTR".

-Most of the people have two copies of the normal allele and produce the functional CFTR protein form.

-Patients with cystic fibrosis have two copies of the mutated allele and so produce the mutated and dysfunctional form for this protein.

-Heterozygote people possess only one normal CFTR allele and a mutated form for the same allele and produce a normal protein and a mutated protein.

In the last case, both alleles are codominant and they express in heterozygote individuals. Given the fact that the normal allele produces enough functional CFTR protein, these individuals do not have any adverse effect and the mutated allele is recessive at a physiological level.
