Tipos de inmunidad

El sistema inmunitario humano se divide en dos grandes categorías: la inmunidad innata y la inmunidad adaptativa. La inmunidad innata actúa como la primera línea de defensa, respondiendo rápidamente, en cuestión de minutos u horas, a las infecciones mediante barreras físicas, químicas y celulares.

Tipos de inmunidad

Name the character


Type in the name of the character whose change throughout the story you are going to analyze.

Example: Nick Carraway.

El sistema inmunitario reacciona a la invasión con dos funciones críticas: detecta al invasor por medio de sensores, y lo ataca con un elaborado mecanismo de respuesta.

cuando tales patrones se detectan en los patógenos, se les denomina patrones moleculares relacionados con patógeno (PAMP)
Reconocen patrones moleculares generales específicos, tales moléculas se denominan receptores de reconocimiento de patrón (PRR)
Combinaciones de azúcares, determinadas proteínas, moléculas portadoras de lípidos específicos, y algunos motivos (estructuras repetitivas) de ácidos nucleicos.

Barreras anatomicas

Secreciones mucosas
Lagrimas
Saliva
Flora bacteriana normal
La piel y las capas epiteliales mucosas son protegidas contra la colonizacion microbiana por una variedad de mecanismos.
Celulares

Macrofagos alveolares

Mecanicos

*Cilios *Grupos de liquidos

Quimicos

*Enzimas *Pepetidos antimicrobianos * pH

Vias urogenitales
Vias respiratorias
Vías digestivas

Adaptativa

Character's behavior

Think of the character's behavior at the beginning of the story and look for the way it changed throughout the story.

Cuenta con respuesta de memoria
Los anticuerpos neutralizan la capacidad del invasor de infectar otras células al tiempo que elevan la probabilidad de que el invasor sea fagocitado por macrófagos y neutrófilos
Tarda días en reaccionar
Las células T citotóxicas detectan y destruyen patógenos que acechan en las células del hospedador

Change in behavior

How did the character change the first behavior you mentioned? Type in a quote to prove your statement.

Example: Nick assumes the whole responsibility for Gatsby's funeral arrangements, 'with that intense personal interest to which every one has some vague right at the end.'

Combate la infección con una respuesta específica a la medida del patógeno atacante.
Celulas presentadoras de antigeno
Linfocitos T

Initial behavior

What is the character's behavior at the beginning of the story? Type in a relevant quote for your statement.

Example: Nick seems to be an honest person, calling himself 'one of the few honest people that I have ever known'.

Linfocitos B

Initial behavior

How does the character act at the beginning of the story? Type in a relevant quote for your statement.

Example: Nick shows his immature side as he leaves to New York in order to avoid 'being rumored into marriage' with his girlfriend.

Innata

Character's feelings

Focus on the way the character's feelings are presented at the beginning and at the end of the story, while explaining why they have changed.

Barreras celulares
serie de células con receptores sensibles que detectan productos microbianos y efectúan un contraataque.

The reason for the change of feelings

What caused the character to change the first belief you mentioned? Type in the reason for the change.

Example: disgust towards the lack of morality in the Buchanan family.

*Fagocitos, *Celulas Nk, *Celulas dendriticas

Células dendríticas inmaduras y macrófagos del tejido invadido tienen diversos receptores

Citocinas

Receptores tipo Toll

Barreras quimicas
Moléculas solubles especializadas con actividad antimicrobiana

Change of feelings

How did the character change the belief you mentioned?

Type in a relevant quote for his change.

Example: 'Winter night and the real snow, our snow(...)We drew in deep breaths of it . . . unutterably aware of our identity with this country for one strange hour before we melted indistinguishably into it again. That's my middle-west.' - Nick on the purity and integrity of Midwest.

Acidez del contenido estomacal

Change of feelings

In what way did the character change the feeling you mentioned?

Type in a quote to support your statement.

Example: 'They are a rotten crowd. You're worth the whole damn bunch put together.' - Nick criticizing the Buchanans.

Barreras fisicas
Membranas mucosas

Initial feelings

What was the character's initial belief? Type in a relevant quote.

Example: 'seems like the ragged edge of the universe' - Nick talking about Midwest, the place where he grew up.

Piel

Initial feelings


How does the character feel about a certain subject at the beginning of the story? Type in a relevant quote to support your statement.

Example: "Reserving judgements is a matter of infinite hope."
